FlyDB is a high-performance key-value storage engine written in Go, based on the bitcask log-structured storage model. It serves as a cost-effective alternative to in-memory stores like Redis by balancing fast read/write performance with cheaper disk-based storage.

Use cases

• embed a fast key-value store in a Go application
• replace Redis where disk-based storage is acceptable
• store key-value pairs with low storage cost
• build a caching layer backed by disk
• learn how bitcask storage engines work
• persist session or metadata as key-value pairs

When to choose

• you need an embedded KV store in Go with fast reads and writes
• you want Redis-like semantics without keeping all data in memory
• your workload fits the bitcask model of append-only writes and in-memory indexes

When to avoid

• you need SQL, joins, or rich queries
• you require multi-node replication or full Raft consensus today
• you need battle-tested production maturity comparable to Redis or RocksDB
