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 KEYS
and DEL
commands together. Here are two common methods for clearing a Redis queue:
DEL
CommandIf you know the name of your queue (e.g., "my_queue"), you can issue the DEL
command to remove it:
DEL my_queue
KEYS
and DEL
CommandsThis 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:
redis-cli KEYS 'queue_*' | xargs redis-cli DEL
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.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
