Keydb Eng — New!
: If your Redis instance is hitting a CPU bottleneck on a single core, KeyDB allows you to utilize the remaining cores on your server.
KeyDB is available through several channels:
keydb-server --port 6379 --server-threads 8 keydb eng
KeyDB is ideal for needing vertical scaling beyond a single core. It maintains Redis compatibility while unlocking multi-core hardware. However, evaluate the operational maturity of your team and tools (monitoring, backup automation) before adopting in critical paths.
By default, KeyDB operates similarly to Redis but utilizes a proprietary multithreaded architecture. : If your Redis instance is hitting a
, an open-source fork of Redis, directly addresses this limitation. Maintained by Snap Inc. and now a part of the broader ecosystem, KeyDB brings multi-threaded execution to the Redis command set, offering a drop-in replacement with significant performance gains.

KeyDB implements a MultiVersion Concurrency Control (MVCC) architecture, a feature rarely seen in NoSQL databases. When the engine needs to update data, it doesn't overwrite the original. Instead, it creates a newer version or snapshot.
Integrates RocksDB directly into the KeyDB core.
