How to empty a redis database?

database nosql redis

You have two options:

database nosql redis

Be careful here.

FlushDB deletes all keys in the current database while FlushALL deletes all keys in all databases on the current host.

database nosql redis

tldr: flushdb clears one database and flushall clears all databases

Clear CURRENT

Delete default or currently selected database (usually `0) with

redis-cli flushdb

Delete specific redis database with (e.g. 8 as my target database):

redis-cli -n 8 flushdb

Delete all redis databases with

redis-cli flushall
