Master-Slave Benefits: When actually deployed, so assigned, the original master (s) was primarily doing data collection, slave (s) doing backup, other work, sharing the main pressure. Read and write separation: In order to load the read operation pressure of master, the slave server can provide the client with read-only service, and the write service must still be comple

Redis sentinel cluster construction and Jedis test graphic tutorial [2], redisjedis In Redis, the establishment of sentinel clusters and the Jedis test graphic tutorial [1] have already written the setup and testing of sentinel clusters in Redis. This chapter mainly describes the sentinel Jedis test in Redis. Generall

The role of __attribute__ (Sentinel) is to remind the programmer that "this variable parameter function requires a null as the last argument." , and this null parameter is generally called the "Sentinel parameter". For example, the following procedure: #include Use GCC Main.c-wall The compilation has no warning. But obviously, the last argument to invoke Foo () should be null to indicate that "there are s

View cluster node information again and execute command after connecting cluster clientCommand: cluster nodes; You can see that 10070 nodes have been deleted. Command: Cluster nodes, you can see that the hash slot for the 10070 node has been assigned to the 10010 node ------------------------------------------------------- ---------------------------------------------------- Sentinel
