• User Guide
• API Documentation
• Cargo Package (axum)

Variants

• PostgreSQL using SQLx, tokio_postgres, and deadpool.
• MongoDB with mongodb.

Notable Points (both performance and build)

• Use of async.
• Use of the most recent versions of Rust, axum and dependencies.
• (Disabled by default) Compile-time swap-in of simd-json instead of serde_json for faster JSON serialization.
• Release binaries are stripped and compiled with CPU native.
• Sockets configured with TCP_NODELAY and to support an increased number of pending connections.
• For very simple benchmarks, use of a separate, single-threaded Tokio runtime for each thread.
• Server configured to serve HTTP/1 only, with no need for websockets.
• Separation of build and deployment containers using multi-stage builds.
• Deployment into Google's minimal distroless-cc container.
• Use of pipelined database queries (where supported).
• Streaming database queries (where supported).
• Use of PostgreSQL prepared statements cache (where supported).
• Use of PostgreSQL arrays to execute multi-row database updates with a single UPDATE query.
  • This is permitted by the test requirements, step (ix).
• Use of a fast PRNG
