Redis, as a high-performance key-value storage service, has always performed well on a single instance, but it has long been lacking in support of an official high-availability solution. As a result, Redis-sentinel came into being, providing high-availability support transparent to clients. The following article systematically explains the principle of Redis-sent

First, overview:sorted-sets and sets types are very similar, both are collections of strings and do not allow duplicate members to appear in a set. The main difference between them is that each member of the sorted-sets has a fraction (score) associated with it, and Redis is sorting the members of the collection from small to large by fractions. However, it is important to note that although the members in the Sorted-sets must be unique, the fractions

Before this function is not concerned, the Memcache data storage method has been used, but since the replacement of Redis, for a hash of data storage and access for Memcache is very convenient, but the problem is, a hash of the list if the amount is not large, With the Hgetall function almost no problem, once the list is more than 50 or more, at this time with the Hgetall function can be very intuitive to see performance problems, there is no data ana
