The release also adds partial indexes as a preview feature for PostgreSQL, SQLite, SQL Server, and CockroachDB, and fixes BigInt precision issues. The post explains why v7 had performance regressions: moving from Rust/Tokio to a WASM module shifted query compilation onto the main JavaScript event loop, causing contention under high concurrency. Query caching addresses this by parameterizing queries and reusing their static structure. Benchmarks show v7.4 outperforms both v6 and v7.3 in requests per second and latency under load. ## Full article daily.dev links to this article rather than hosting it.
