tidesdb-java is the official Java binding for TidesDB.

TidesDB is a fast and efficient key-value storage engine library written in C. The underlying data structure is based on a log-structured merge-tree (LSM-tree). This Java binding provides a safe, idiomatic Java interface to TidesDB with full support for all features.

• MVCC with five isolation levels from READ UNCOMMITTED to SERIALIZABLE
• Column families (isolated key-value stores with independent configuration)
• Bidirectional iterators with forward/backward traversal and seek support
• TTL (time to live) support with automatic key expiration
• LZ4, LZ4 Fast, ZSTD, Snappy, or no compression
• Bloom filters with configurable false positive rates
• Global block CLOCK cache for hot blocks
• Savepoints for partial transaction rollback
• Six built-in comparators plus custom registration
