How to clean all Redis data: Redis 2.8 and later: The FLUSHALL command deletes all key-value pairs. Redis 2.6 and earlier: Use the DEL command to delete keys one by one or use the Redis client to delete methods. Alternative: Restart the Redis service (use with caution), or use a Redis client (such as flushall() or flushdb()).

How to clean all Redis data

Redis is an open source, high-performance cache and database system. There are several ways to clean all Redis data, depending on the version of Redis you are using.

For Redis 2.8 and later:

• FLUSHALL command:

  • This will remove all key-value pairs in Redis.
  • Execute this command: FLUSHALL

For Redis 2.6 and lower:

• DEL command:

  • This will delete the specified key.

  • To delete all keys, you need to do the following:

    • Get a list of all keys: KEYS *
    • traverse the keys and delete them one by one: DEL some-key

Other methods:

• Using the Redis client:

  • Many Redis clients provide methods to delete all keys. For example, in the Redis client:

    • flushall()
    • flushdb()

• Restart Redis service:

  • This will erase all data and restart Redis.
  • Warning: This method is not recommended in production environments because it can cause service interruptions.

Use with caution:

Before cleaning Redis data, make sure you have the correct understanding. This is because cleaning Redis data is irreversible and all stored data will be lost.

To avoid accidental data loss, it is recommended that you back up your Redis database before making any changes.
