website hash slot Hash Slot Algorithm Redis uses a hash slot algorithm to determine which shard or node a specific key belongs to The algorithm divides the hash slot 5 Hashing Hash Functions Given a collection of items, a hash function that maps each item into a unique slot is referred to as a perfect hash function
hash slot Hash Slot을 이용한 데이터 분산 Redis는 16384개의 hash slot으로 key 공간을 나누어 관리; 각 키는 CRC16 해싱 후 16384로 modulo 연산을 해 각 hash There are two ways to allocate hash slots in the redis cluster: take out an appropriate number of hash slots on other nodes and allocate There are 16384 hash slots in Redis 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
