February 2026 (Month: 2026-02) — tursodatabase/turso Summary focus: delivering stronger data integrity, broader SQL compatibility, and a richer type system. The team advanced DDL capability, extended query and inspection tooling, and laid groundwork for robust STRICT/custom-type models. These efforts reduce risk during migrations, improve interoperability with SQLite tooling, and expand business-ready data modeling options across the product. Key achievements span data integrity, SQL compatibility, and type-system maturity: - CHECK constraints implementation with DDL support and enforcement, including handling for DROP COLUMN and RENAME COLUMN edge cases to preserve data integrity (commit 7cb4b65a6ea85495190adb7b9751b090cf81bc28 and related fixes). - REGEXP operator support added, translating REGEXP to regexp() calls and exposing an extension-based implementation for extensibility and compatibility with SQLite semantics. - Expanded PRAGMA and metadata exposure: table_list, index_list, index_info, and index_xinfo behavior aligned with SQLite; tests updated for MVCC compatibility and compatibility docs updated. - PostgreSQL-compatible types bootstrapped at startup (12 types: boolean, varchar, date, time, timestamp, smallint, bigint, inet, bytea, uuid, json, jsonb) with corresponding encoder/decoder and operator mappings; improved type validation and compatibility. - Core type system hardening and introspection: sqlite_turso_types virtual table backed by an in-memory type registry; types loaded at startup and accessible via PRAGMA/list-types and dumps; groundwork for CREATE TYPE / DROP TYPE improvements and type-encoded values across the engine. - MVCC improvements for attached databases: per-database MVCC transactions to isolate work across multiple databases in a single session, improving concurrency and correctness when using ATTACH. Overall impact: stronger data integrity guarantees, broader database compatibility with SQLite and PostgreSQL-like features, and a more capable type system enabling safer custom types and richer data modeling. These changes position Turso for safer migrations, easier integration with existing tooling, and expanded business value through advanced data types and robust constraints. Technologies/skills demonstrated: Rust-based SQL engine development, DDL/DDL-edge-case handling, SQL-extensibility (REGEXP), MVCC for multi-database scenarios, in-memory type registry design, virtual tables, and extensive test and documentation work to improve reliability and interoperability.
