No envelope received in Akka projection when I delete a durable state

Akka Libraries
1

Hello,

I am using Akka projection (1.5.4) with JDBC (PostgreSQL). My source is DurableStateSourceProvider.changesByTag. I get a DurableStateChange.UpdatedDurableState envelope when I do an Effect.persist(state) in my Durable state actor.

The problem is that I do not get any envelope when I do an Effect.delete(), the handler is not called. The StatusObserver.beforeProcess() is also not called for a deletion. On the other hand, it is called for a change.

This is very strange, because I expect to get an envelope with DurableStateChange.DeletedDurableState inside when I do an Effect.delete().

Did I misunderstand something?

Thank you for your help.

I’m afraid this could be a bug. Implement Delete effect for DurableState · Issue #686 · akka/akka-persistence-jdbc · GitHub

Hi @patriknw

Thank you for your response.

After checking in Akka persistence JDBC plugin code, it appears that this is not implemented at all.
