† Parse stage only (pre-tokenized input to AST), SELECT id, name FROM users, Apple M4, Go 1.27, median of 10 runs of BenchmarkPerformanceBaseline. Complex queries take longer (see performance_baselines.json). Reproduce: go test -run ^$ -bench BenchmarkPerformanceBaseline -benchmem -count=10 ./pkg/sql/parser/.
What is GoSQLX?
GoSQLX is a production-ready SQL parsing SDK for Go. It tokenizes, parses, and generates ASTs from SQL with zero-copy optimizations and intelligent object pooling - parsing a simple SELECT in about 318 ns (~3.1M parses/sec).
Why GoSQLX?
- Not an ORM - a parser. You get the AST, you decide what to do with it.
- Not slow - zero-copy tokenization, sync.Pool recycling, no allocations on hot paths.
- Not limited - PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, SQLite, Snowflake, ClickHouse. CTEs, window functions, MERGE, set operations.
- Not just a library - CLI, VS Code extension, GitHub Action, MCP server, WASM playground, Python bindings.
