Stooplap v0.2 released today as this SQLite alternative for providing embedded SQL database needs while written in the Rust programming language. Stoolap supports both in-memory and persistent storage models.

Stoolap supports MVCC transactions and is fully ACID compliant while being written entirely in Rust. With Stoolap 0.2 there is more work on features like additional grouping sets, Volcano-style operator architecture, SEMI/ANTI join operators, query timeout support, keyset pagination, and other functionality.

Stoolap 0.2 also brings a number of performance optimizations for its query execution, storage and MVCC handling, much faster JOINs, various memory/allocation enhancements, index optimizations, and also underlying architecture improvements.
