Redis provides a rich command to manipulate databases and various data types, which can be used on Linux endpoints.

Redis Common management commands: bgrewriteaof Asynchronously (asynchronously) rewrites the AoF file to reflect the state of the current database.

The Bgsave command returns OK immediately after execution, then
The Flushall flushdb command clears the data and never fails, which is dangerous for online clusters. The KEYS * command, when used when the data scale is large, can seriously affect redis performance and is very dangerous. What if these risks are fundamentally circumvented? Redis provides a very simple and efficient way to set the disable commands directly in
