When you use a transaction or script to run a command on a Tair cluster instance, the requested keys must be in the same slot. Solution: Modify the transaction or script. You can use the CLUSTER KEYSLOT command to query the slot in which a requested key is stored. Important Tair ...

The following table describes DCS's support for read/write splitting.For a Redis Cluster instance, you can query all master and replica nodes by running the CLUSTER NODES
readOnlyFromClient过程: processInputBuffer--->processCommand--->call 唤起后lookupCommand会去redisCommandTable中找命令 Redis的启动方式: 直接启动./redis-server& 指定配置文件启动./redis-server/etc/redis/6379.conf 使用redis启动服务配置开机自启动
cluster默认是不支持slave节点读或者写的,跟我们手动基于哨兵搭建的主从架构不一样的,需要手动带上readonly这个指令,这个时候才能在slave node进行读取。默认的话就是读和写都到master上去执行的,redis cluster模式下就不建议做物理的读写分离了,建议通过master的水平扩容,来横向扩展读写吞吐量,还有支撑更多的海量数据。
Redis Redis(Remote Dictionary Server ),即远程字典服务,是一个开源的使用ANSI C语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库,并提供多种语言的API。 redis是当前最热门的NoSQL技术之一。 Redis 是一个开源(BSD
