TerarkDB is a RocksDB-compatible embedded key-value storage engine forked from RocksDB v5.18.3, offering improved tail latency, throughput, and compression. It can be used as a drop-in replacement for RocksDB in C/C++ applications on Linux.

Use cases

• replace rocksdb with a faster kv store
• reduce tail latency in embedded key-value storage
• migrate existing rocksdb data to a better engine
• improve compression for large-value workloads
• embed a high-performance storage engine in a c++ application

When to choose

• you already use RocksDB on Linux and want better performance without changing your API
• your workload is read-heavy or write-heavy with large values and needs lower tail latency
• you want better compression in an embedded KV store

When to avoid

• you need production support on platforms other than Linux
• you need language bindings beyond C/C++
• you may need to migrate data back to RocksDB, which is not supported
