Fix Redis Data Not Deleting: Persistence Guide
If data still exists after deletion in Redis, the issue may be due to the persistence mechanism of Redis. There are two ways of persistence in Redis: RDB snapshots and AOF logs. If persistence is enabled, it could be that the data has already been persisted to the disk, making the delete operation ineffective.
The solution is as follows:
- Do not save the changes made.
Make the file append-only. - Manually delete persistent files: Stop the Redis service, delete the files storing snapshots and AOF logs, and then restart Redis.
- Clear all data from the current database.
- Delete key
If the above methods still do not solve the problem, it may be due to Redis’s data synchronization mechanism causing unsynchronized data. You can try restarting the Redis service or checking the Redis log files to troubleshoot the issue. If the problem persists, it is recommended to contact Redis official technical support or consult the official documentation for more assistance.
