Eng __hot__ — Keydb

: Unlike Redis's single-threaded model, KeyDB uses spinlocks to guard the core hash table, allowing network I/O and query parsing to happen concurrently across multiple CPU cores.

: Distributes work across all available CPU cores to maximize hardware efficiency. keydb eng

The engineering decisions—from thread-affinity sockets to checkpointing without fork() —reveal a deep understanding of OS internals, memory allocators, and concurrent data structures. While not a panacea, KeyDB proves that the "single-threaded for simplicity" argument has an expiration date. For workloads that can embrace its sharded model, KeyDB unlocks the latent power of today’s 64-core servers. : Unlike Redis's single-threaded model, KeyDB uses spinlocks
