Announcement of Reliability focused 147th DevClub.lv

Posted onOctober 16, 2025November 10, 2025AuthorAnete ValaineLeave a comment

HI!

We all want our systems to be fast and reliable — but what does reliability really mean?
At our newest meetup, we’ll go deep into the layers that make it possible: from runtime internals and microservices design to real-world reliability practices from Google-scale systems.

You are welcome to Reliability focused event on Thursday, October 23, 18:30, at GoCardless office – Marijas iela 2a, Novira Plaza, entrance “East”, 3rd floor.

Please, register here!

Agenda for Reliability focused 147th DevClub.lv

Dmitrijs Zubriks from GoCardless will give a talk “What your language runtime doesn’t tell you about threading”
This session unwinds the layers of Ruby MRI to reveal what really happens beneath a programming language’s abstractions. Using a simple thread creation call as a starting point, the talk dives into CRuby’s internals with an outlook at the underlying machinery in action.
The entire execution path will be traced, beginning with a single line of code, following the process as it’s transformed into bytecode, creates a native OS thread, and interacts with the VM’s core scheduling components.
Attendees will gain an understanding of how threads are managed at the system level, how the Global VM Lock coordinates execution, and how language runtimes interact with the operating system behind the scenes. While the talk uses CRuby as an example, the concepts apply to most language runtimes with an interpreter lock, and will provide insights into how high-level abstractions map to system-level operations.
(Language – English)
Tags: Ruby, CRuby, MRI, Concurrency, Performance, Systems Programming, Runtime Internals

Dmitrijs is a Principal Software Engineer at GoCardless with more than 15 years of experience spanning DevOps, Programming, and Performance Optimizations. He leads technical initiatives and specializes in diving deep into system internals and understanding how systems work beneath the abstractions.

Aleksejs Truhans from Google will give a talk titled “Why is my app SLOw? Defining reliability in platform engineering”
Platform engineering is all fun and games until platform customers start complaining about their apps running slowly. Is it the app code or the platform? This talk looks at how Google’s Serverless SRE team detects platform-level latency regressions before users, measures the impact of regressions, and tracks performance over time. We’ll discuss the limitations of SLOs in this context and how to take a statistical approach that gives a customer-centric picture of the performance of our platform instead.
(Language – English)
Tags: SLOs, Reliability, SRE

Aleksejs has 28 years of experience in engineering and leadership roles, and currently is an SRE team manager at Google.

Oleg Anastasyev from 01.tech will give a talk “Building Efficient and Reliable Microservices”
Building a large microservices infrastucture can be a challenging task, especially when its is loaded with hundreds of thousands requests per second, each of them shouldd be served with as low latency as possible.
In this talk we’ll explore the approach to build services as stateful applications – they store their data locally, embedding a Cassandra database into the application’s JVM process. This challenges the usual way of building applications – a stateless microservice with a separate remotely accessible database cluster.
In this talk Oleg will try to cover the advantages of stateful vs stateless microservices, discuss how statefulness affects reliability and accessibility of services and how it helps to build faster applications. We’ll go step-by-step through building a stateful application service, delving into its architecture, major components as well as significant challenges and their solutions.

HI!

As you may know MySQL is celebrating its 30th anniversary! Our next event, this time taking place on WEDNESDAY, is dedicated to this occasion.

You are welcome to MySQL 30th anniversary focused event on WEDNESDAY, October 8, 18:30, at C.T.Co office – Meistaru iela 33, Valdlauci, Kekavas parish, Kekavas district.

Agenda for “MySQL 30th anniversary” focused 146th DevClub.lv

Vittorio Cioe from Oracle MySQL will give a talk “The full stack approach: Supercharge your apps with MySQL, JavaScript and REST APIs… all in one!”
Unleash the full potential of your applications with a modern, full-stack approach.
This presentation dives into the powerful synergy between MySQL, JavaScript, and REST APIs. We’ll chart MySQL’s evolution from a traditional database to a cornerstone of modern microservices, and explore how JavaScript is integrated directly into the DBMS to revolutionize stored programs. You’ll then discover how to transform your data into a powerful asset by creating and consuming REST APIs natively within MySQL, making the information you already own both accessible and actionable.
This isn’t just about updating a stack—it’s about utilizing MySQL’s full potential to build a foundation for scalable, high-performance applications.
(Language – English)
Tags: Database, MySQL, DevOps, REST, Javascript, AI

Vittorio is a Solution Engineer at Oracle, specializing in MySQL presales across CEE, Iberia, Israel, Turkey and South Africa.

Fluent in six languages, he is expert and passionate about open source technologies, databases, performance tuning, and digital transformation, helping enterprises optimize their technology stacks through innovative solutions.

Max Morokko from GoCardless will give a talk titled “How Meta Made MySQL Work at Scale.”
In this session, we will explore how Meta evolved MySQL and its system design to handle tremendous scale. Using the user feed feature as a case study, we’ll trace the journey from a basic solution to Meta’s approach, applying principles such as replication, sharding, denormalization, caching, database layer abstraction, and indexing.
(Language – English)
Tags: MySQL, Databases, Scalability

Max is an Engineering Director with 18 years of experience in technology, entrepreneurship, and management. He currently leads the Connectivity group at GoCardless and previously worked at Facebook/Meta as a Solutions Engineer.

Aytaj Guliyeva from Accenture will give a talk “When ORMs Don’t Save You: What Developers Should Really Watch Out For”
ORM frameworks like Sequelize and Prisma are trusted by developers to prevent SQL injection and simplify database work. But as security reviews show, these frameworks sometimes fail in ways that aren’t obvious at first glance.
In this session, you will discover how hidden operator injections, unsafe defaults, and subtle framework quirks can lead to exploitable situations – even in tools designed to protect you. You will learn where assumptions about ORM safety can quietly backfire and what small coding decisions make the biggest security difference.
Aytaj will share real-world cases where ORMs didn’t behave as expected, along with practical lessons you can carry into your own projects. The goal is not to turn you into security experts, but to give you the awareness to know what to question and where to look if something doesn’t feel right in your code.
