Summary
Comprehensive optimization of system performance: acceleration of work with the database through indexing and transition to ORJSON to reduce the load on the CPU during serialization.
What has changed:
Database: Added indexes for all Foreign Keys in order and inventory models, as well as for the field critical for background tasks
expires_at. This eliminates Sequential Scan when clearing expired reservations.Serialization: The
orjson(Rust) library has been implemented as a standard serializer for FastAPI (ORJSONResponse).Middleware: The work of the idempotency decorator has been optimized - reading and writing the cache in Redis now occurs through
orjson, which gives an increase in speed on highly loaded endpoints.Logging: Configured
structlogusingorjsonto render logs in JSON.
