I am using Redis version 6.0.7 and adopting the hash storage method. Approximately 3,000 keys are stored, with each key corresponding to a hashmap. Each hashmap contains roughly 100 to 1,000 key-value pairs. Under the circumstance that no one has deleted the data, some data in the hashmap has gone missing. Redis has not been restarted, and no one has been found to have deleted the keys; there are no anomalies in the Redis logs.

How did you determine that no one deleted the entryies in the hashes? I've seen quite a lot of hdel commands.
