To empty a specific Redis database, you can use the “FLUSHDB” command. This command removes all the keys from the current database.
You can run the command in the redis-cli by typing:
$ redis-cli FLUSHDB
You can also use the python redis library to empty a specific Redis database:
import redis
r = redis.Redis()
r.flushdb()
It’s important to note that before using the FLUSHDB command you have to select the database you want to empty using the SELECT command, for example:
$ redis-cli SELECT 0
$ redis-cli FLUSHDB
This command first selects the database 0 and then empties it.
Please be careful when using this command, as it will permanently delete all data stored in the current selected database.
