If you want data persistence in your Go application, most likely you’re thinking of using some database. The easiest and probably the most convenient for deployment are embedded databases. There are many wrappers for C databases, however Go developers usually prefer pure Golang solutions.
Bolt is the way to go: it’s a pure Go embedded key/value database, which is easy to use for persistence in your Go projects. Bolt is similar to LMDB, which many consider the best among state-of-the-art modern key-value stores. Just like LMDB, and unlike LevelDB, BoltDB supports fully serializable ACID transactions. Unlike SQLite, it doesn’t have a query language, and is much easier to use for common things.
Bolt saves data into a single memory-mapped file on disk. It doesn’t have a separate journal, write-ahead log, or a thread for compaction or garbage collection: it deals with just one file, and does it safely.
