As a side effect of the command execution, the node may go into down state because not all hash slots are covered. *Example. The following command removes the association for slots 5000 and 5001 from the node receiving the command: > CLUSTER DELSLOTS 5000 5001 OK *Usage in Redis Cluster [ERR] Not all 16384 slots are covered by nodes ...

Redis cluster tutorial – Redis The redis-cli cluster support is very basic so it always uses the fact that Redis Cluster nodes are able to redirect a client to the right node. A serious client is able to do better than that, and cache the map between hash slots and nodes addresses, to directly use the right connection to the right node. redis-cluster - add-node slave to existing cluster from ...

So 16k was in the right range to ensure enough slots per master with a max of 1000 maters, but a small enough number to propagate the slot configuration as a raw bitmap easily. ...

Redis 集群数据共享¶. Redis 集群使用数据分片（sharding）而非一致性哈希（consistency hashing）来实现： 一个 Redis 集群包含 16384 个哈希槽（hash slot）， 数据库中的每个键都属于这 16384 个哈希槽的其中一个， 集群使用公式 CRC16(key) % 16384 来计算键 key 属于哪个槽， 其中 CRC16(key) 语句用于计算键 key 的 CRC16 ... redis集群试验（单机and 多机） - 龙壹的博客 | BY Blog redis-cli是redis默认的客户端工具，启动时加上`-c ...

Of course you may also setup a service IP to failover together with redis.
