Cluster mode
The Nats cluster mode is not transparent to the client.So the cluster has an impact on both the publisher and the Subscriber.Both the Publisher and the Subscriber know that a clustered service is connected, not a single point of service, in other words, the Publisher Subscriber must indicate the address of each node in the cluster.Of course, pu

Data partitioningRedis clusters store data on multiple nodes, that is, different partitions are stored on different nodes, and each node can store multiple partitions. Each partition is also referred to as a "hash slot" in Redis, with a total of 16,384 partitions planned in the Redis cluster. For example: when there are 3 nodes in a cluster, Node A will contain 0-5460 partitions, Node B will contain 5461-10
The Redis cluster is an assembly that provides data sharing between nodes in multiple Redis. redis3.0 Previously, only support master-slave synchronization, if the main hang, write on the problem. 3.0 will be a good way to help us solve this problem.At present, Redis 3.0 is not stable, if you want to use in the production environment, be cautious.
