How to set an expiration time?

for some reason, I need to set an expiration time for the snapshot. so how to configure the plugin?
Thanks for you work.

Do you mean the timestamp field in SnapshotMetadata when saving a snapshot? I think it's only used optionally when searching for a snapshot. It defaults to 0L and this plugin should store the value as is.

No. For there is not enough redis space for the snapshot, so it is prudent to create a process to clean up some data after a period of time. Thanks for your reply.

Just so I understand correctly, are you suggesting to add ability in this plugin to specify a timeout (Redis TTL) on a snapshot? Snapshots are stored in a Sorted Set with persistenceId as key. Redis can only expire the entire Set, meaning all snapshots under the same persistenceId will be lost. An alternative solution could be to have an actor that cleans up snapshot by calling deleteAsync with a timestamp.

I tried the function: deleteSnapshots(criteria: SnapshotSelectionCriteria), and it didn't work.
