集群支持hash tags功能,即可以把一类key定位到同一个节点,tag的标识目前支持配置,只能使用{},redis处理hash tag的逻辑也很简单,redis只计算从第一次出现{,到第一次出现}的substring的hash值,substring为空,则仍然计算整个key的值,这样对于foo{}{bar}、{foo}{bar}、foo这些冲突的{},也能取出tag值。使用者需遵...
That module might not always be able to find a specific key in a tree when doing a lookup. In this case, it makes sense to expect the user to deal with unknown results: they could use a default value, check to insert a new one, delete the tree, etc. This is when it's ...

另外一个局限是,在slot迁移过程中,multi-key命令特别容易报错(CROSSSLOT Keys in request don’t hash to the same slot)。建议不用multi-key命令。 6、扩容速度慢。redis官方提供了redis cluster管理脚本redis-trib.rb。使用该脚本进行扩容cluster的时候,是串行的迁移slot中的每个key,这样导致了 ...
“Whenever I talk to chief scientific officers at major device companies, they talk about the lack of data and their inability to know what is happening with their products after they sell them and when problems arise. Their hands are tied just like everybody else’s. . . . They...
