Redis has created a new way of storing data. When using redis, we don't have to focus on how to put elephants in the refrigerator in the face of monotonous databases, instead, redis uses flexible data structures and data operations to build different refrigerators for different elephants. Common redis Data Types

Redis is a high-performance key-value database. The emergence of redis largely compensates for the shortage of keyvalue storage such as memcached, and can play a very good complementary role in relational databases. It provides Python, Ruby, Erlang, PHP, and Java clients for ease of use.Redis uses a single-thread IO multiplexing model and encapsulates a simple AeEvent event processing framework, which mainl

200 Redis instances on a server, and it crashes. The only way to do this is to make different types of data belong to different applications and separate from each other.So, is there a way for Redis to keep different application data separate from each other and stored on the same instance? is equivalent to the MySQL database, different application data is stored under different databases.Under

clients are more mature and stable in terms of client support at present. and Redis because its protocol itself is more complex than memcached, plus the author constantly add new features, and so on, the corresponding third-party client tracking speed may not catch up, sometimes you may need to make some changes on the basis of third-party clients to better use.According to the above comparisons it is not difficult to see that when we do not want the
