FAQs
What happens if I do not use ACL SAVE
after modifying ACL rules?
If you do not save the ACL rules after modifications, the changes will not persist after the Redis server is restarted, leading to potential security risks.

can fail if there are issues with writing to the aclfile
, such as permission errors or disk space issues. Ensure that Redis has the necessary permissions and sufficient disk space.
