bbolt is an ACID-compliant embedded key-value store for Go applications. It persists all data in a single memory-mapped file on disk, organizing information using B+ trees to facilitate sorted key iteration and efficient range queries.
The project distinguishes itself through a hierarchical data organization model, allowing buckets to be nested within other buckets to create a tree-like structure. It employs a single-writer, multi-reader locking mechanism and copy-on-write transactions to ensure serializable isolation and data integrity.
The system includes comprehensive data management capabilities, such as unique identifier generation, cursor-based iteration, and hot backup generation. Maintenance tools are provided for database compaction, consistency verification, and the repair of corrupted pages.
Command-line utilities are available for querying database content and inspecting internal structural metadata.
