Ruben Fiszel dfd08d8a4b refactor: improve usage table behavior to eliminate synchronous row locks (#6863)
* refactor: improve usage table behavior to eliminate synchronous row locks

Replace synchronous INSERT...RETURNING with SELECT + async UPDATE pattern:
- Add check_usage_limits() to read current usage without row locks
- Add increment_usage_async() to update usage in background task
- Refactor job push logic to use optimistic validation
- Simplify job completion tracking with better error handling

This eliminates blocking row locks on the usage table during job creation,
significantly improving throughput and reducing contention.

Note: Requires running 'cargo sqlx prepare' with database access to update
the query cache in .sqlx/ directory.

* Update SQLx metadata

* refactor: optimize cloud usage checks with caching and conditional queries

- Add 60s cache for superadmin status checks to reduce DB load
- Skip unnecessary user usage query for premium workspaces
- Use existing team plan status cache (already implemented in windmill-common)
- Update check_usage_limits to accept check_user_usage parameter
- Add sqlx query cache for conditional user usage query

This optimization eliminates redundant database queries during job creation,
particularly for premium workspaces where user usage tracking is not needed.

Windmill Backend

This folder holds all backend components, the src/ folder only contains files used to build the "root" binary.

Components

name description
windmill-api The API server, exposing functionality to other components and the frontend
windmill-audit Contains audit functionality, allowing different components to record important actions
windmill-common Common code shared by all crates
windmill-queue Contains job & flow queuing functionality, commonly written to by the API server and read from by workers
windmill-worker The worker. Used to process and execute flows & jobs.
parsers Contains code to parse signatures in different langauges.

Compile sqlx for offline ci
