Redis (4) for beginners-Sort Redis cache and redis
Before implementing the cache sorting function, you must first clarify the rationality of this function. Now that you can sort data in the database, why do you need to put the sorting function in the cache? The following two reasons are briefly summarized: first, sorting increases the load on the database and is

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
