Question: How to Clear Redis Database?

Answer

To clear the Redis database, you have two main options:

1. FLUSHDB: This command clears the current Redis database.
2. FLUSHALL: This command clears all databases in the Redis instance.

Here's a brief overview of both commands and how to execute them.

1. FLUSHDB

FLUSHDB removes all keys from the currently selected database. To use this command, simply enter it in the Redis CLI:

redis-cli FLUSHDB

You can also use it via a Redis client in your programming language, such as Python with redis-py:

import redis

r = redis.StrictRedis(host='localhost', port=6379, db=0)
r.flushdb()

2. FLUSHALL

FLUSHALL removes all keys from all databases within the Redis instance. To use this command, enter it in the Redis CLI:

redis-cli FLUSHALL

You can also use it via a Redis client in your programming language, such as Python with redis-py:

import redis

r = redis.StrictRedis(host='localhost', port=6379, db=0)
r.flushall()

Note: Use these commands with caution, as they will delete data permanently.
