How to permanently remove key from KV store or ignore deleted keys in Watcher?

[RomanKuznetsov-hz]

Hi there!
I have two .NET applications:

1. puts and deletes entries to KV store. KV store never being deleted.
2. watches all keys in this KV store applies changes from if.

The problem:
When consumer application starts to Watch KV store, it gets deleted keys (as they stay in KV store) as well as not deleted.
I need to handle deletion that was made AFTER subscription, but I don't need to handle all previously deleted keys (there can be items deleted a year ago for instance).
If I set option NatsKVWatchOpts.IgnoreDeletes = true I will not get deleted events at all that is not an option.

I don't see any option to permanently remove key from KV store.

Any advice?

NATS server 2.11.5
NATS.Net 2.5.2

As you’re on 2.11 you could use the new TTL options (can’t remember the exact name of them off hand) . This will purge your deleted entries after the TTL and remove all the tombstones.
