To clear a Redis queue, you can use the
DEL command which deletes a key from the database. If you want to delete multiple keys, you can use the
DEL commands together. Here are two common methods for clearing a Redis queue:
If you know the name of your queue (e.g., "my_queue"), you can issue the
DEL command to remove it:
This method is useful if you have multiple queues with a shared pattern in their names (e.g., "queue_*"). First, find all the keys matching the pattern using the
KEYS command, and then use the
DEL command to delete them.
In the Redis CLI, you can use a loop to achieve this:
Note: Be cautious when using this method as it may unintentionally delete keys you don't intend to remove. Always verify that the pattern matches only the intended keys before executing the command.
Remember, both methods will delete the entire queue, meaning that the data stored within those keys will be lost. Make sure to backup any important data before executing these commands.
