  <h1>Stoolap Documentation</h1>

  <p>Welcome to the Stoolap Documentation! This is your comprehensive guide to using and understanding Stoolap, a high-performance embedded SQL database written in pure Rust.</p>

  <h2>What is Stoolap?</h2>

  <p>Stoolap is a modern embedded SQL database that provides full ACID transactions with MVCC, a sophisticated cost-based query optimizer, and features that rival established databases like PostgreSQL and DuckDB. Built entirely in Rust with minimal unsafe code (only for FFI and performance-critical hot paths), Stoolap features multiple index types (B-tree, Hash, Bitmap, HNSW), native vector search with semantic search support, parallel query execution, and comprehensive SQL support including window functions, CTEs, and temporal queries.</p>
