Databases Written in Go

52 projects

This subcategory lists databases whose engines are written in Go. Some are standalone servers you deploy, such as distributed SQL and time series databases. Others are embedded libraries that store data in files inside your own process, which is often what a Go developer is really looking for when building a tool, agent or single-binary service.

Among servers, TiDB is a distributed SQL database compatible with the MySQL protocol, and CockroachDB is a distributed SQL database that speaks the PostgreSQL wire protocol. Dolt is a MySQL-compatible database with Git-style branching and merging. rqlite replicates SQLite with Raft. Prometheus and VictoriaMetrics store metrics as time series, Dgraph is a graph database and Milvus is a vector database for embeddings. Among embedded stores, etcd's bbolt is a B+tree key-value store in a single file, Dgraph's badger is an LSM-tree store, and CockroachDB's pebble is a RocksDB-inspired engine. goleveldb has been quiet since 2024, while rosedb and immudb offer other designs.

For embedded storage, bbolt suits read-heavy workloads that value simplicity and transactions, while badger and pebble suit write-heavy workloads. If you need SQL in-process, an SQLite driver may be simpler than any key-value store. For servers, check each project's license as well as its features, since some database vendors have moved away from open-source licenses.
