About Redis redis is a high-level Key-value database. It is similar to memcached, but the data can be persisted and the supported data types are rich. There are 5 types of strings, linked lists, hashes, collections, and ordered collections. Support

Before leader triggers failover, wait a few seconds (then 0~5) for other Sentinel instances to prepare and adjust. If all is well, then leader needs to start upgrading a salve to master, which must be in a good state (not in the Sdown/odown state)

First, prefaceBecause Redis is being used in recent projects, a deep understanding of redis design and implementation is needed in order to better understand redis and apply it in the appropriate business scenarios.My analysis process is based on

PrefaceIn Redis, set and list are string sequences, very similar, except that set is to use a hash table to maintain the uniqueness of the string, no order, not like a list, can be deleted and removed data. But set also has its own corresponding

PrefaceReasoning feel that the list in Redis is nothing to write, if the operation of a few commands is too tedious, so in the end I will be based on the Redis list data type special properties, while comparing the mature Message Queuing product

Redis is a memory-based high-performance Key-value database, which is stored in memory and periodically flushed to disk for high read and write efficiency. He is characterized by support for various data structures, stirng,hashes, list,set, and

One, the company is now using the cluster scheme (REDIS+SENTINEL)Monitoring a Redis cluster together with multiple Sentinel detects that Master is not available and polls to determine if master needs to switch. Sentinel detects each other (by

PrefaceThe biggest difference between Redis and memcached is that, in addition to supporting data persistence, Redis supports more data types than just simple key-value structure data records. Redis also supports more server-side operations on these

　　　We all know that Redis is developed in C language, so in c it means that string is in the char[] array, and then you might think, that's not easy, when I execute the following command, it's definitely straight.The char[] array to be plugged
