Please make the kvStore watcher async #744

Open thierryba opened 4 months ago

thierryba commented 4 months ago

Proposed change

make another call to watch for keys that sets up a callback. Today kvStore_Watch and kvStore_WatchAll are blocking, which is not ideal.

Use case

If I want to watch different values from 1 or more buckets, today I have 2 solutions:

create N threads
listen to the $KVSTORE subjects and do it manually (but it is not perfect and does not for instance get the initial value)
