The primary differentiator of KeyDB is its multi-threaded architecture. While traditional in-memory stores like Redis are primarily single-threaded for command execution, KeyDB utilizes multiple threads to handle network IO and query processing simultaneously. This architectural shift allows KeyDB to fully utilize modern multi-core processors, often achieving significantly higher throughput on a single instance compared to its single-threaded counterparts. Introduction The defining characteristic of KeyDB is its

• High memory usage: COW can duplicate 2-3x the dataset during writes.
• Latency spikes: On large machines, fork() itself can take milliseconds, and subsequent page faults disrupt latency.
