Redis Cluster and Partitioning - inovex-Blog The Redis Cluster will distribute your dataset among multiple nodes and will add availability by using a master-slave model.In the figure above we have three master nodes and the 16384 hash slots are divided between those instances (crc16 of key modulo 16384).[OK] All 16384 slots covered. Redis DB - Re: Can't reshard my node. Slots not all… The following uncovered slots have no keys across the cluster: ./redis-trib.rb:410:in `fix_ slots_coverage': undefined method `keys' for #
Redis Cluster does not use consistent hashing, but a different form of sharding where every key is conceptually part of what we call an hash slot. 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.
Node-to-node communication happens exclusively using the Cluster bus and the Cluster bus protocol: a binary protocol composed of frames of different types and sizes. The Cluster bus binary protocol is not publicly documented since it is not intended for external software devices to talk with Redis Cluster...

Redis cluster. Quick overview. ... Redis has a tool for connecting nodes called redis-trib.rb. And yes, ... [OK] All 16384 slots covered. Redis cluster with cross replication | There is no magic here *** This is not possible with 3 nodes and 2 replicas per node. *** At least 9 nodes are required. (redis-trib is an “official” tool to create a Redis cluster) The important point here is that all of the Redis tools operate with Redis instances, not nodes, so it’s your responsibility to put the instances in the right redundant topology. Redis Cluster with pre-existing data - fnordig.de [OK] All 16384 slots covered. We now have a Cluster consisting of 3 master nodes, with all 16384 slots only assigned to the first instance. Setting a key on this instance works fine. Every other node will report a MOVED error: $ redis-cli -p 7001 set foo bar OK $ redis-cli -p 7002 set foo bar (error) MOVED 12182 127.0.0.1:7001
