The one-sentence definitions

• Data Warehouse: Curated, schema-on-write, SQL-first analytics store for clean, conformed data and BI.
• Data Lake: Cheap, flexible object storage for raw + semi-processed data with schema-on-read.
• Data Lakehouse: A lake with warehouse guarantees (ACID tables, governance, performance), letting you run BI + ML on the same storage.

Big picture: how they treat data

“Mental model” diagrams (add these as images in Medium)

Image 1: Classic Warehouse

[CRM/ERP/Kafka] --> [ETL/ELT] --> [Warehouse tables] --> [Dashboards/Exports]

A pipeline pushing cleaned data into warehouse tables used by BI.

Image 2: Classic Lake

[All sources] --> [Raw zone] --> [Cleansed/curated zones] --> [Spark/Trino/ML]

Multi-zone data lake with raw and curated folders, queried by engines.

Image 3: Lakehouse

[All sources] -> [Object store + ACID table format] -> [SQL BI + ML on same tables]
                     (Iceberg/Delta/Hudi + Catalog)

Lakehouse with ACID table format and a catalog, serving BI and ML.

If you want polished visuals, add three simple diagrams: “Warehouse,” “Lake,” and “Lakehouse,” each showing sources, storage, and consumers.

Why the lakehouse emerged

Warehouses were great for governed BI but expensive and rigid for raw/ML data. Lakes were cheap and flexible but lacked transactions, versioning, and performance metadata. A lakehouse uses open table formats (e.g., Apache Iceberg, Delta Lake, Hudi) to add:

• ACID transactions (safe concurrent writes/reads)
• Table evolution (add/rename columns safely)
• Time travel/versioning (reproducibility)
• Stats, partitioning, and indexing (speed)
• Catalog integration (discovery, governance)

Concrete examples

Data Warehouse (SQL BI)

• Use case: Monthly revenue, close-the-books, executive dashboards.
• Pattern: Ingest → Transform to conformed dimensions/facts → BI.
• Example SQL:

SELECT d.date, p.category, SUM(o.revenue) AS rev FROM fact_orders o JOIN dim_date d   ON o.date_key = d.date_key JOIN dim_product p ON o.product_key = p.product_key WHERE d.date BETWEEN '2026-01-01' AND '2026-01-31' GROUP BY 1,2;

Data Lake (raw+ML)

• Use case: Keep all raw logs, one-off data science, feature engineering.
• Pattern: Land everything in object storage → read with Spark/Trino → write derived Parquet.

Data Lakehouse (unified)

• Use case: BI + ML on the same tables without copying.
• Pattern: Land → write ACID tables in Iceberg/Delta/Hudi → query with engines (Spark/Trino/Snowflake/Synapse/BigQuery external) → govern via a catalog.

Where the catalog fits (crucial for a lakehouse)

A catalog is the system of record for tables: namespaces, schemas, locations, versions, permissions. Examples include Hive Metastore, AWS Glue, Unity Catalog, Nessie, or a vendor catalog.

• In a warehouse, the catalog is native to the platform.
• In a lake, you add one (or you suffer from “bucket-sprawl”).
• In a lakehouse, the catalog + table format is what makes “warehouse-like” governance possible on your lake.

Typical architectures

Warehouse-centric

• Ingest → ELT → Warehouse tables → BI
• Pros: Excellent BI reliability/perf
• Cons: Raw/ML data lives elsewhere (duplication)

Lake-centric

• Everything to lake → Engines read from lake
• Pros: Low cost, flexible formats
• Cons: Without ACID/catal og, governance and concurrency are hard

Lakehouse-centric (modern)

• Lake storage + Iceberg/Delta/Hudi + catalog
• Pros: BI + ML on shared data with ACID & governance
• Cons: You must operate/choose the right table format & catalog

Costs & performance (rules of thumb)

• Storage: Lake/lakehouse uses cheap object storage; warehouse storage is pricier.
• Compute: Warehouse optimizes for SQL; lakehouse narrows the gap via table stats, manifests, clustering, and caching.
• Copy cost: Lakehouse reduces “copy silos” (warehouse extract for BI + separate ML lake). Fewer copies = lower ops cost and fewer sync bugs.

When to choose which

Use this checklist:

• BI with tight SLAs, finance-grade governance?
• Start warehouse or lakehouse (with mature table format).
• Heavy ML/DS, diverse data types (JSON, images, logs) at low cost?
• Start lake or lakehouse.
• You want one storage layer for BI and ML, with time travel, ACID, and catalog governance?
• Lakehouse.

Many teams end up hybrid: a lakehouse as the source of truth, plus a small, performance-tuned warehouse mart for critical dashboards.

Migration patterns (practical)

1. Warehouse → Lakehouse

Land raw to lake; rebuild curated marts as ACID lakehouse tables; point BI to them (or export a slimmed mart back to the warehouse if needed).

2. Lake → Lakehouse

Convert Parquet folders to ACID tables (Iceberg/Delta/Hudi), register in a catalog, add schemas/constraints/tests, then enable SQL BI.

3. Greenfield

• Start lakehouse: object store + table format + catalog; pick engines (Spark/Trino/DBT) for transform + BI tool on top.

Gotchas & anti-patterns

• Copy-on-copy: Maintaining separate “BI copy” and “DS copy” silently doubles spend and drifts.
• No catalog: Buckets full of Parquet with no catalog = unfindable, ungoverned data.
• No compaction: Append-only writes without compaction degrade performance.
• Schema chaos: Enforce contracts; use table schema evolution tools with review.

A tiny “hello world” with a lakehouse table (Iceberg flavor)

Conceptual example — adjust for your engine.

-- Create an Iceberg table in your catalog/namespace
CREATE TABLE lakehouse.sales_orders (
  order_id        BIGINT,
  customer_id     BIGINT,
  order_ts        TIMESTAMP,
  status          STRING,
  amount          DECIMAL(12,2)
)
PARTITIONED BY (bucket(16, customer_id))
TBLPROPERTIES ('format-version'='2');

-- Insert data (from a staging Parquet/CSV)
INSERT INTO lakehouse.sales_orders
SELECT * FROM staged_orders;
-- Time travel (yesterday's snapshot)
SELECT * FROM lakehouse.sales_orders
FOR SYSTEM_TIME AS OF TIMESTAMP '2026-01-15 00:00:00';

Conclusion

• Warehouse: curated, strict, BI-ready.
• Lake: cheap, flexible staging/ML playground.
• Lakehouse: best of both — open storage plus ACID, governance, and performance so BI and ML share the same truth.

If you share your cloud (AWS/GCP/Azure), BI/ML priorities, and current tools, I can sketch an opinionated reference architecture (with exact table format + catalog choice) and a 90-day migration plan.

Data Warehouse vs. Data Lake vs. Data Lakehouse was originally published in Tech Wrench on Medium, where people are continuing the conversation by highlighting and responding to this story.

Authentication is the act of proving identity. It shows up everywhere: logging into an app, connecting to a server, or letting one service call another. What trips people up is that “authentication” is a bucket term — different mechanisms solve different problems, and it’s common to use more than one in the same system.

Below are four widely used mechanisms, what they’re best at, and where they fit.

Consider ByteByteGo’s popular System Design Interview Course for your next interview!

Use these visuals in your post if you’d like:

• Download image: Four Common Authentication Mechanisms
• Download image: How These Mechanisms Show Up in Real Systems

1) SSH Keys

SSH keys are a public/private key pair used primarily for secure access to remote machines. Instead of sending a password across the network, your client proves it holds the private key that matches a public key the server already trusts.

Where SSH keys shine:

• Admin access to Linux servers
• Secure Git access over SSH
• Automated jobs that need strong machine access without interactive login

Common mistakes:

• Reusing the same key everywhere
• Leaving keys unprotected on developer laptops
• Skipping key rotation and inventory

Practical best practices:

• Use passphrases (or hardware-backed keys) where possible
• Use short-lived certificates or centralized key management in larger orgs
• Disable password login if SSH keys are the intended method

Don’t waste hours on Leetcode. Learn patterns with the course Grokking the Coding Interview: Patterns for Coding Questions.

2) OAuth Tokens

OAuth is most useful when you want delegated access. In plain terms: a user authorizes an app to do something on their behalf without handing over their password.

OAuth tokens are designed for:

• Third-party integrations (e.g., “Let this app read my calendar”)
• Fine-grained permission scopes (read-only vs write access)
• Expiring access that can be revoked

Common mistakes:

• Treating tokens like “forever credentials”
• Issuing overly broad scopes by default
• Storing tokens insecurely on clients or logging them

Practical best practices:

• Prefer short-lived access tokens with refresh tokens when needed
• Keep scopes minimal and explicit
• Rotate and revoke aggressively when abuse is detected

3) SSL/TLS Certificates

SSL/TLS certificates are about secure communication and identity at the transport layer. When you connect to a website over HTTPS, TLS encrypts traffic and helps confirm you’re talking to the right server.

Typical uses:

• HTTPS between clients and servers
• Service-to-service encryption inside a company network
• Mutual TLS (mTLS) where both sides authenticate each other

Common mistakes:

• Letting certificates expire
• Relying on TLS alone when application-level auth is still required
• Mismanaging trust stores and certificate chains

Practical best practices:

• Automate certificate issuance and renewal
• Use mTLS where service identity matters (especially inside zero-trust networks)
• Monitor expiry dates and handshake failures proactively

4) Credentials

“Credentials” is the broad category that includes passwords, API keys, shared secrets, and similar login material. They’re simple and ubiquitous, but they’re also the easiest to mishandle.

Where credentials show up:

• Username/password sign-in
• API keys for service access
• Shared secrets between systems

Common mistakes:

• Hardcoding secrets in source code
• Reusing the same secret across environments
• Never rotating keys because “nothing has gone wrong yet”

Practical best practices:

• Use a secrets manager (not plaintext config files)
• Rotate regularly and on any suspected exposure
• Add rate limiting and anomaly detection around credential-based endpoints
• Prefer stronger alternatives (mTLS, short-lived tokens) for machine-to-machine access

How to Choose the Right One

A quick way to decide is to start with the scenario:

• Need encrypted communication and server identity? Start with TLS certificates.
• Need remote server admin access without passwords? Use SSH keys.
• Need a user to grant limited access to an app without sharing their password? Use OAuth tokens.
• Need a straightforward login or API access method? Use credentials, but manage them like high-risk assets.

Most production systems combine these. For example:

• TLS secures the connection.
• A token or credential authenticates the caller at the application layer.
• SSH keys secure admin access for operations.

Closing Thought

“Authentication” isn’t one tool. It’s a set of tools you choose based on who needs access, what they should be allowed to do, and how safely you can manage the proof of identity over time.

If you want, paste your target audience (beginners vs engineers vs security-minded readers), and I’ll tune the article’s depth and examples to match.

SystemDesignNotes — high quality system design interview prep that gets you in, at Big Tech!

OOPs (Object-Oriented Programming) concepts carry great significance in interviews, spanning a wide range of product-based and service-based companies. Being well-versed in these concepts is crucial as they are frequently inquired about during job interviews. Following is a compilation of the top 50 OOPs interview questions, providing detailed coverage of essential topics to effectively prepare you for the interview requirements of most companies.

Don’t waste hours on Leetcode. Learn patterns with the course Grokking the Coding Interview: Patterns for Coding Questions.

1. What is OOPS?

OOPS stands for Object-Oriented Programming system, where programs are viewed as a collection of objects. Each object represents an instance of a class.

2. Write basis concepts of OOPS

The key OOPS concepts are:

Abstraction

Encapsulation

Inheritance

Polymorphism

3. What is a class?

A class serves as a representation of a specific object type. It acts as a blueprint, plan, or template that defines the details and characteristics of an object.

4. What is an Object?

An object is an instance of a class. It possesses its unique state, behavior, and identity.

5. What is an Encapsulation?

Encapsulation is an attribute on an object, and it contains all data which is hidden. That hidden data can be restricted to the members of that class. Levels are public, protected, private, internal, and protected internal”

6. What is Polymorphism?

Polymorphism is the concept of assigning different behaviors or values in a subclass to something that was already declared in the main class. In simple terms, it allows a single function or variable to take on multiple forms or meanings.

Consider ByteByteGo’s popular System Design Interview Course for your next interview!

7. What is Inheritance?

Inheritance is a concept that enables one class to inherit the structure and behavior defined in another class. When a class inherits from just one class, it is known as Single Inheritance, and when it depends on multiple classes, it is referred to as Multiple Inheritance.

8. What are Manipulators?

Manipulators are functions that can be utilized in combination with the insertion (<<) and extraction (>>) operators on an object. Notable examples include endl and setw.

9. Explain the term constructor

A constructor is a method utilized to initialize the state of an object, and it is automatically invoked during the creation of the object. The rules governing constructors are as follows:

• The constructor name must be identical to the class name.
• Constructors must not have a return type.

10. Define Destructor?

A destructor is a method which is automatically called when the object is made of scope or destroyed. The destructor’s name is the same as the class name but preceded by the tilde symbol (~).

11. What is an Inline function?

An inline function is a compiler technique that directs it to insert the complete body of the function wherever the function is used in the program’s source code.

12. What is a virtual function?

A virtual function, as a member of a class, allows its functionality to be overridden in its derived class. This feature is accomplished by using the keyword “virtual” during function declaration. In C++, virtual functions can be declared using the “virtual” token. In C/Python languages, this behavior can be achieved through function pointers or pointers to functions.

13. What is a friend function?

A friend function is a special function that has the privilege of accessing public, private, or protected data within the class it is declared as a friend. However, if the function is defined outside the class, it does not have access to such information. A friend can be declared anywhere within the class declaration and remains unaffected by access control keywords such as private, public, or protected.

14. What is a function overloading?

Function overloading involves creating multiple methods with the same name in a program, each capable of handling different parameters. This approach allows functions to vary based on the type of input and output they can accept. For instance:

void add (int& a , int& b);

void add (double& a, double& b);

void add (struct bob& a, struct bob& b);

15. What is operator overloading?

Operator overloading is a concept in which different operators can be applied and their behavior depends on the arguments provided. Operators like +, -, and * can be passed through a function, and each operator has its own precedence for execution.

16. What is an abstract class?

An abstract class is a class that cannot be directly instantiated, meaning you cannot create objects of it. However, it can be inherited by other classes. An abstract class can exclusively contain abstract methods. In Java, only abstract methods are allowed in an abstract class, while other programming languages may permit non-abstract methods as well.

17. What is a ternary operator?

A ternary operator is an operator that takes three arguments, where the arguments and results can be of different data types, based on the function’s requirements. This operator is also known as a conditional operator.

18. What is the use of finalize method?

The Finalize method aids in performing cleanup operations on currently utilized resources. This method is marked as protected, making it accessible solely within the class itself or by a derived class.

19. What are the different types of arguments?

A parameter is a variable declared in the function or subroutine, while arguments are passed to the function body and must correspond with the defined parameters. There are two types of arguments:

• Call by Value: The value passed is modified only within the function, and it returns the same value irrespective of what was passed into the function.
• Call by Reference: The value passed is modified both inside and outside the function, and it may return the same or a different value.

20. What is the super keyword?

The super keyword is employed to invoke the superclass method that has been overridden by a subclass. This keyword facilitates access to overridden methods and hidden members of the superclass. Additionally, it can be used to forward a constructor call from a subclass to a constructor in the superclass.

21. What is method overriding?

Method overriding is a feature that enables a subclass to furnish its own implementation of a method that already exists in the main class. By using the same method name, the same parameters, and the same return type, the implementation in the superclass is effectively replaced by the one in the subclass.

22. What is an interface?

An interface comprises abstract methods. When a class implements an interface, it inherits all the abstract methods defined in that interface. Java employs interfaces to achieve multiple inheritances.

23. What is exception handling?

An exception is a circumstance that arises while a program is running. Exceptions encompass various types, such as Runtime exceptions and Error exceptions. These instances are effectively managed using exception handling mechanisms like try, catch, and throw keywords.

24. What are tokens?

A compiler identifies tokens as indivisible units that cannot be further dissected. Tokens encompass keywords, identifiers, constants, string literals, and operators. Additionally, even punctuation characters are recognized as tokens, including examples like brackets, commas, braces, and parentheses.

25. What is the main difference between overloading and overriding?

Overloading involves static binding, whereas overriding involves dynamic binding. Overloading refers to the utilization of the same method name with varying arguments, and it may or may not yield the same output within the same class. On the other hand, overriding pertains to the usage of identical method names, arguments, and return types in both a class and its derived class.

26. What is the main difference between a class and an object?

An object is an instance of a class. Objects encompass various data, whereas classes themselves lack inherent data. Properties and functions can be defined within a class and subsequently utilized by objects. Classes can give rise to sub-classes, whereas objects do not give rise to sub-objects.

27. What is an abstraction?

Abstraction is a valuable aspect of object-oriented programming (OOP) that presents only essential information to an object’s user. This means it reveals solely the pertinent information about an object, excluding its internal constructors. For instance, when operating a television, comprehending the intricate circuitry or mechanisms behind its activation is unnecessary. Abstraction employs abstract classes to display only the necessary functionalities needed to switch on the TV.

28. What are the access modifiers?

Access modifiers define the extent to which methods or variables can be reached from different objects or classes. There exist five categories of access modifiers, enumerated as follows:

. Private

. Protected

. Public

. Friend

. Protected Friend

29. What are sealed modifiers?

Sealed modifiers are access modifiers that prevent methods from being inherited. Sealed modifiers can also be employed with properties, events, and methods. This modifier cannot be utilized with static members.

30. How can we call the base method without creating an instance?

Yes, it’s feasible to invoke the base method without needing an instance, provided the method is defined as ‘static’. This can be accomplished when inheriting from that class by utilizing the ‘Base’ keyword within a derived class.

31. What is the difference between new and override?

The ‘new’ modifier guides the compiler to utilize a new implementation in place of the base class function. Conversely, the ‘override’ modifier allows for the replacement of the base class function with a new implementation.

32. What are the various types of constructors?

There exist three kinds of constructors:

• Default Constructor: Without any parameters
• Parametric Constructor: With parameters, enabling the creation of a new instance of a class while simultaneously passing arguments.
• Copy Constructor: Generates a fresh object identical to an existing object.

33. What is early and late Binding?

Early binding involves assigning values to variables during the design phase, whereas late binding involves assigning values to variables at runtime.

34. What is ‘this’ pointer?

‘THIS’ pointer points to the present object within a class. The ‘THIS’ keyword functions as a pointer, distinguishing the current object from the global object. It signifies the current object.

35. What is the difference between structure and a class?

The inherent access type for a Structure is public, while for a class, it’s private. Structures are employed to group data, whereas classes serve the purpose of grouping both data and methods. Structures are dedicated to data and don’t necessitate rigorous validation, whereas classes are utilized for encapsulating and inheriting data, demanding stringent validation.

36. What is the default access modifier in a class?

The default access modifier of a class is Internal and the default access modifier of a class member is Private.

37. What is a pure virtual function?

A pure virtual function is a function that can be overwritten in a derived class but remains undefined itself. A virtual function can be designated as pure using the ‘=0’ operator.

Example:

Virtual void function1 { } // Virtual, not pure

Virtual void function2 { } = 0 // Pure virtual

38. What are all the operators that cannot be overloaded?

The operators listed below cannot undergo operator overloading:

• Scope Resolution (::)
• Member Selection (.)
• Member selection through a pointer to function (.*)

39. What is dynamic or run time polymorphism?

Dynamic or runtime polymorphism, often referred to as method overriding, involves resolving the call to an overridden function during runtime rather than at compile time. This entails having two or more methods with identical names, signatures, but distinct implementations.

40. Do we require a parameter for constructors?

No, constructors do not necessitate parameters.

41. What is a copy constructor?

This serves as a unique constructor designed to generate a new object mirroring an already existing object. There exists a solitary copy constructor, which can either be user-defined or provided by the system.

42. What does the keyword virtual represented in the method definition?

This implies that we can override the method.

43. Whether static method can use nonstatic members?

False.

44. What are a base class, subclass and superclass?

he base class is the most general class, often considered as the root class. A subclass is a class that inherits characteristics from one or more base classes. The superclass is the parent class from which another class derives its inheritance.

45. What is static and dynamic Binding?

Binding refers to the linkage of a name with a class. Static Binding, also known as early binding, establishes this linkage between the name and class during compile time.

Dynamic Binding is a binding in which name name can be associated with the class during execution time, and it is also called as Late Binding.

46. How many instances can be created for an abstract class?

No instances are generated for an abstract class. In simpler terms, it’s not possible to create an instance of an abstract class.

47. Which keyword can be used for overloading?

Operator keyword is used for overloading.

48. What is the default access specifier in a class definition?

Private access specifier is used in a class definition.

49. Which OOPS concept is use as a reuse mechanism?

Inheritance is an object-oriented programming concept employed for the purpose of reusability.

50. Which OOPS concept exposes only the necessary information to the calling functions?

Encapsulation concept exposed the necessary information to the calling functions.

Poor Man’s System Design Interview Prep — an alternate to paid resources

Don’t waste hours on Leetcode. Learn patterns with the course Grokking the Coding Interview: Patterns for Coding Questions.

ChatGPT model is a large language model trained by OpenAI that is capable of generating human-like text. You can engage in conversations and obtain human-like responses from ChatGPT. By simply providing the prompts and pasting as input for ChatGPT, it will generate responses that would continue the conversation or expand on the given prompt. Below are list of 50 awesome ChatGPT prompts to get started with and begin exploring ChatGPT capabilities:

1. Act as position Interviewer

I’d like you act as an interviewer. I’ll be the candidate, and you’ll ask me the interviewer’s questions about the job. I’d like you to respond only as an interviewer. Do not attempt to write all of the discussions at once. I only want you to do interviews with me. Ask me the questions and then wait for my responses. Do not include explanations. Ask me the questions one by one, as an interviewer would, and wait for my responses. ‘Hello,’ is my first sentence.

Examples: IOS Developer, Full Stack Developer, React Frontend Developer, Node.js Backend etc.

2. Act as an Excel Sheet

I’d like you to serve as a text-based Excel spreadsheet. You will only respond to me with a text-based excel 10 row spreadsheet with row numbers and cell letters as columns. (A to L). The first column header should be left blank to reference row number. I’d tell you what to put in info cells, and you’d respond with solely the results of excel tables as text. Do not include explanations. I’d write you formulas, you’d execute them, and you’d only respond with the outcome of an excel table as text. First, start with an empty sheet.

3. Act as an English Pronunciation Helper

I’d like you to help Turkish speakers with their English pronunciation. I’ll compose you sentences, and all you have to do is respond to their pronunciations. The responses must be pronunciations rather than translations of my speech. For phonetics, Turkish, Latin letters should be used in pronunciation. Do not include explanations in responses. ‘How is the weather in Istanbul?’ is my first sentence.

4. Act as a Plagiarism Checker

Please serve as a plagiarism checker for me. I’ll write you sentences, and you should only respond in that sentence’s language to avoid being flagged for plagiarism checks. Answers should not include explanations. My first line reads, “Speech recognition systems must be able to process nonverbal information, such as the emotional state of the speaker, for computers to behave like humans.

5. Act as a ‘Character’ from ‘Movie/ Book/Anything’

Act like the {character} from the {series} please. I want you to respond and answer with the voice and vocabulary that {character} would use. Write no justifications in your letter. Only respond with {character}. You must be fully knowledgeable about {character}. My opening line is “Hello, {character}.”

Examples:

Character: Harry Potter, Darth Vader , Series : Harry Potter Series, Star Wars etc

6. Act as an Advertiser

I want you act as an advertiser. You would design a campaign to advertise your chosen commodity or service. You would select a target market, create key messaging and slogans, decide on the media channels to use for promotion, and make any other decisions necessary to achieve your objectives. My first I need assistance developing an advertising campaign for a new type of energy drink that targets young folks between the ages of 18 and 30.

7. Act as a Storyteller

I want you to act as a storyteller. You’ll think of amusing tales that the audience will find interesting, imaginative, and intriguing. It could be fairytales, informational tales, or any other kind of story that has the power to hold readers’ interest and imagination. For example, if you’re giving stories to youngsters, you might talk about animals; if you’re delivering stories to adults, you could find that history-based tales are more interesting to them. My first request is for a compelling story on preservation.

8. Act as a Stand-up Comedian

Rule # 3

When working with a write intensive system, its recommended of use a Message Queue for Async processing.

Rule # 4

If ACID compliance is required for a system, it is advisable to opt for a Relational Database Management System (RDBMS) or SQL Database.

Rule # 5

If the data is unstructured and does not necessitate compliance with ACID properties, best option is a NO- SQL Database.

Rule # 6

If the system has intricate data such as videos, images, files, etc., it is recommended to consider utilizing Blob/Object storage

Rule # 7

When a system requires intricate pre-computation, such as for a news feed, employing a combination of Message Queue and Cache is advisable.

Rule # 8

If the system has to search through a lot of data, consider utilising a search index, tries, or a search engine like Elasticsearch.

Rule # 9

If the system calls for scaling the SQL database , we should take Database Sharding into consideration.

Rule # 10

When the system necessitates High availability, Performance, and Throughput, using a Load Balancer is advisable.

Rule # 11

If a system requires swift global data delivery, as well as reliability, high availability, and superior performance, it would be recommended using a to CDN.

Rule # 12

If the system contains data containing nodes, edges, and relationships like friend lists, road connections, and so forth, use of a Graph Database should be taken into consideration.

Rule # 13

When a system requires scaling of multiple components, such as servers and databases etc, using Horizontal Scaling is advisable.

Rule # 14

If a system requires high-performance database queries, we should think about using Database Indexes.

Rule # 15

If the system needs to process jobs in bulk, consider using Batch Processing and Message Queues.

Rule # 16

If the system needs to reduce server load and stop DOS attacks, use a Rate Limiter.

Rule # 17

If the system has microservices, consider using API Gateway (Authentication, SSL Termination, Routing etc).

Rule # 18

If the system has a single point of failure, implementing Redundancy in that component is advisable.

Rule # 19

If the system needs to be fault-tolerant, resilient, and long-lasting, Data Replication (creating multiple copies of data on different servers) should be used.

Rule # 20

For achieving fast user-to-user communication (bi-directional) in the system, using Websockets is recommended.

Rule # 21

In case the distributed system requires the capability to identify malfunctions, it is advisable to incorporate a Heartbeat.

Rule # 22

If the system needs to assure data integrity, use the Checksum Algorithm.

Rule # 23

If the system needs to transport data across other servers in a decentralised manner, it is recommended to utilize the Gossip Protocol.

Rule # 24

Consistent Hashing should be used if the system needs to scale servers with the addition and removal of nodes efficiently and without hotspots.

Rule # 25

Think about using Quadtree, Geohash, etc. if the system needs to deal with anything related to a place, such as maps or nearby resources.

Poor Man’s System Design Interview Prep — an alternate to paid resources

Set aside the 10,000-Hour Rule, and my apologies to Mr. Gladwell. A few years after Malcolm Gladwell’s book ‘Outliers’ was published, I encountered it and had a shift in perspective.

Within the book, Gladwell highlights a theory presented by researcher Anders Ericsson called the 10,000-Hour Rule:

“The key to achieving true expertise in any skill is simply a matter of practicing, albeit in the correct way, for at least 10,000 hours.”

Upon digesting this, a sense of unease settled in. It felt as though I was already lagging behind. Fortunately, not long after this ‘Outliers’-induced dilemma, I stumbled upon a TED Talk by Josh Kaufman. Josh provides illumination on how the 10,000-Hour Rule has been misinterpreted over time.

What people assume it means:

To become proficient in a skill, you need to put in 10,000 hours of practice.

What it truly signifies:

Accumulating 10,000 hours of practice is required to reach the top 1% in a particular field.

In actuality, Josh discovered that acquiring a reasonable proficiency in a new skill can often be accomplished in around 20 hours. Moreover, when these 20 hours are utilized effectively, the rate of learning can become remarkably accelerated.

Here’s a step-by-step approach to help you achieve this:

1. Dissect the skill

Analyze the skill’s fundamental principles, concepts, and their interconnections. By doing so, you’ll develop a well-defined path for acquiring knowledge and tackling the skill. Consider applying the 80/20 Rule (Pareto Principle).

Instances of the Pareto Principle in action:

• 80% of your business comes from 20% of your clients
• The wealthiest 20% of investors hold 80% of your company’s assets
• Around 20% of your focused effort accounts for 80% of your work’s outcomes”.

2. Acquire sufficient knowledge for self-correction’

After establishing a foundational comprehension of the subject, commence active practice. While practicing, be attentive to your vulnerable areas, where errors occur, and the aspects necessitating improvement.

Consider employing this strategy: The Feynman Method

Stage 1: Choose and study a topic.

Stage 2: Explain the topic to someone, like a child, who is unfamiliar with the topic and at their level of understanding. Use simple language

Stage 3: Identify any gaps in your understanding

Stage 4: Return to the literature to understand better

3. Eliminate practice barriers

Set up an environment that paves the way for your success. Eliminating obstacles allows you to fully concentrate on the task at hand and maximize your practice time. Give these strategies a try:

• Emphasize quality over recentness
• Utilize the Forest app
• Track your productivity
• Establish clear boundaries
• Make use of OneTab
• Engage in meditation
• Harness voice commands
• Silence notifications
• Understand your personal tendencies
• Choose the suitable medium
• Work with a single screen
• Incorporate background noise

4. Dedicate the Time (Strategically)

All practice does not hold the same value. Deliberate practice holds the answer. This involves establishing precise objectives, receiving instant feedback, and challenging yourself for enhancement.

Experiment with this approach:

• Employ a timer
• Use spaced repetition
• Seek feedback
• Grant yourself rewards’
