What each one is

The product in its own terms, so the numbers below have context.

etcd

Leader

etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure.

Independently observed

KeyDB

KeyDB is an open-source database that offers significantly higher performance than Redis through multithreading while maintaining full Redis protocol compatibility. It includes advanced features like active replication, FLASH storage, and MVCC architecture for non-blocking queries.
