Why Redis doesn't support TTL at field level of a Hash

[Kushagra Bindal]

Hi,

We are setting expiration of hash keys at key level. But we have observed that it is not getting expired. Is there any defect or limitation around the same or any way by which we can achieve the same.

Regards

For redis hashes its key expires, not its member.

I guess this is a  feature request and it has been refused by the redis community  because of memory overhead.

I found an older discussion https://groups.google.com/g/redis-db/c/44NWMLanGdI.

i hope that helps.

There is a redis module can set TTL and version for hash field.

The module's name is TairHash.
