How Redis Cluster Maintains Availability while Re-Sharding

Scaling a High-traffic Rate Limiting Stack with Redis Cluster redis hash slot The Redis cluster has 16384 hash slots Each key is checked modulo 16384 after CRC16 verification to determine which slot to place Each node in the cluster is redis hash slot There are 16384 hash slots in KeyDB Cluster, and to compute what is the hash slot of a given key, we simply take the CRC16 of the key modulo 16384 Every node
