How to delete all data in a hash in Redis?

To delete all the hash data in Redis, you can use the DEL command to remove specific hash keys. If you want to delete all the hash data, you can use the SCAN command to iterate through all hash keys and delete them one by one.

Here are the specific steps:

1. Use the SCAN command to iterate over all hash keys.

SCAN 0 MATCH *

This will return a list containing hash keys.

1. Iterate through the list of hash keys returned, and use the DEL command to delete each hash key.

DEL hash_key

The hash_key is the name of the hash key.

Repeat the steps until all hash keys are deleted, then all hash data in Redis can be removed.
