FAQ
Q: What happens if the key does not exist?
A: No error is thrown; Redis simply ignores the delete request.
Q: Can I delete multiple keys at once?
A: This action deletes one key at a time. For multiple keys, use multiple Delete Key actions or a Redis script.
Q: Does deleting a key free memory immediately?
A: Yes. Once deleted, Redis frees the space allocated to the key.
