There are so many values, I want to remove them all or some. How can I do this?

Solution 1

You can use DEL command to remove any key from redis database, regardless of the datatype associated with it.

DEL key [key ...]

Removes the specified keys. A key is ignored if it does not exist.

Solution 2

DEL will allow you to remove the key entirely: http://redis.io/commands/del.

ZREM will allow you to remove members from the set: http://redis.io/commands/zrem.

There are additional ZREM* commands that allow the removal of ranges of members - see ZREMRANGEBYLEX, ZREMRANGEBYRANK and ZREMRANGEBYSCORE

Solution 3

You use the "del" command to remove an entry from redis:

del test

See: http://redis.io/commands/del
