Release Target

Q/A

For mapping changes:

• I ran make after making the schema changes, and committed all changes
• If these field(s) are "exception"-able, I made a companion PR to Kibana adding it (see Readme)
• If this is a metadata change, I also updated both transform destination schemas to match

For Transform changes:

• The new transform successfully starts in Kibana
• The corresponding transform destination schema was updated if necessary

if this is just a new subset of fields in file events and not a new data_stream, we don't need a new top level custom_subset for persistence.

We should probably just have another section for Persistence under the existing file.yml file. Similar to this: https://github.com/elastic/endpoint-package/blob/main/custom_subsets/elastic_endpoint/file/file.yaml#L152

[kevinlog]

if we're not introducing a new data_stream, this shouldn't get created by make. It's being made here because there is a new top level custom_subset for persistence.

By addressing this comment: https://github.com/elastic/endpoint-package/pull/336/files#r1090819658 - it should clean this up with another make clean and make all

[kevinlog]

Checked it out and tried, LGTM.

I'm able to install the package and see the new mappings:

I can see the sample event streams in successfully and I can see the data:
