Notes

App caching:

PoC implemented
Good performance improvement for supervisory node retrieval (4.5s to 0.1s)
Next steps?
- Worth looking into build-in caching support for Spring Boot
- Still need to investigate db caching
This was implemented on the controller layer (caching DTOs)

Angola contributions:

We will probably be getting way more contributions to core than we used to in Malawi
We will work on many core tickets
Josh: we should always get a sign-off from core to implement something; by default go through the tech committee; pull requests just for small changes/tweaks
Wes: consider talking about how we treat external contributions in general
What about testing changes from the external team?
- We certainly might have a gap here
- Rely on close collaboration with the teams to ensure we have the software properly tested (agree with Angola who is testing the change and how)
Consider having a separate call about this (maybe with the Angola team?)

Feature flags:

Approach to removing feature flags (when?)

Package lock files concerns:

dev-ui was updated to support the package-lock files
some of the services are not using them and package-lock files are ignored
why do we have package-lock file in .gitignore?
- the file changed with each build

Action Items

@Sebastian Brudziński to schedule a call with @Josh Zamor (Deactivated) and @Paulina Buzderewicz to talk about the concerns and next steps for App caching

@Mateusz Kwiatkowski to schedule another call with @Josh Zamor (Deactivated) or move it to the next tech committee to talk about feature flags more

@Chongsun Ahn (Unlicensed) to create a ticket to unignore the package-lock
