BadgerDB is a fast, embeddable key-value database written entirely in Go. Applications use it as an in-process storage engine rather than communicating with a separate database server.
Badger is optimised for SSDs and large datasets. Its design combines an LSM tree with a separate value log to reduce write amplification while supporting transactional and versioned access to stored data.
This is free and open source software.
Key Features
- Embeddable persistent key-value database written entirely in Go.
- Requires no Cgo dependencies.
- Concurrent ACID transactions with serializable snapshot isolation.
- LSM-tree architecture with a separate value log.
- Optimised for SSD storage and datasets spanning terabytes.
- Sorted key iteration and prefix-based traversal.
- Direct access to historical versions of values.
- Configurable retention of multiple versions for each key.
- Database snapshots.
- Time-to-live support for automatically expiring entries.
- Command-line utility for offline backup and restoration.
- Native directory locking and fsync support on Linux and other POSIX systems.
