Each request opened and closed its own Postgres connection which added a
big overhead. The goal is to add Django's native psycopg pool behind a new
DB_PSYCOPG_POOL_ENABLED settings with explicit min/max size and keepalive.
Each pool lives in one process, and gunicorn's sync workers serve a single
request at a time which means that a given worker won't use more than one
connection. The default pool minimum size is set to 1, which keeps always
one connection open and the maximum size to 3 as headroom for code touching
the database from an extra thread.
Pooled connections can sit idle for hours, so TCP keepalives are enabled
to keep load balancers and NAT from dropping them silently, and each
connection is health checked on checkout so a broken one is replaced
instead of failing the request.
I have updated all references of "Impress" to "Meet".
Migrations were manually updated and not regenerated. Never-mind,
they all will be squashed before the first release.
I have also searched for reference to "Magnify", and replaced them
by "Meet".
While updating the backend sources, I have also fixed other parts of
the project, namely:
- Compose file
- Github documentation and CI
- Makefile commands
This commit introduces a boilerplate inspired by https://github.com/numerique-gouv/impress.
The code has been cleaned to remove unnecessary Impress logic and dependencies.
Changes made:
- Removed Minio, WebRTC, and create bucket from the stack.
- Removed the Next.js frontend (it will be replaced by Vite).
- Cleaned up impress-specific backend logics.
The whole stack remains functional:
- All tests pass.
- Linter checks pass.
- Agent Connexion sources are already set-up.
Why clear out the code?
To adhere to the KISS principle, we aim to maintain a minimalist codebase. Cloning Impress
allowed us to quickly inherit its code quality tools and deployment configurations for staging,
pre-production, and production environments.
What’s broken?
- The tsclient is not functional anymore.
- Some make commands need to be fixed.
- Helm sources are outdated.
- Naming across the project sources are inconsistent (impress, visio, etc.)
- CI is not configured properly.
This list might be incomplete. Let's grind it.
