This article describes the system cache component, which uses NoSQL Redis as the system cache layer.I. BACKGROUNDThe system takes into account high concurrent usage scenarios. For concurrent submission scenarios, this is addressed through the RABBITMQ component described in the previous section. For the system high concurrency query, in order to provide performance to reduce the database pressure, we join the cache mechanism, can join the cache suppor

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 Ae

Redis persistence and redis persistence Redis has two persistence Methods: Snapshot (RDBFiles) and append files (AOFFile) RDB persistence is used to save a data snapshot at a specific interval. The AOF (Append only file) Persistence method records the write operations received by each server. When the data is replied, the operations of these records are execut

memcached such key/value storage, in some cases can be a good complement to the relational database. It provides clients such as Java,c/c++,c#,php,javascript,perl,object-c,python,ruby,erlang, which is convenient to use. [1] Redis supports master-slave synchronization. Data can be synchronized from the primary server to any number of slave servers, from the server to the primary server that is associated wi
