How to clear data with redis

Here are two ways to clear data in Redis:

1. FLUSHALL command

The FLUSHALL command clears all keys and values ​​in the Redis database. After executing this command, the database will be cleared.

 <code>redis-cli FLUSHALL</code>

2. CONFIG RESETSTAT command

CONFIG RESETSTAT command resets all states in the Redis database, including keys and values. This has the same effect as the FLUSHALL command, but it will also reset other statistics (such as the number of connections).

 <code>redis-cli CONFIG RESETSTAT</code>

Notice:

• Before performing any data clearing operations, it is highly recommended to back up your Redis database first.
