When shutting down an ActorSystem, I would like to shut down a ShardRegion in three phases to ensure consistency:
1. Prevent sharded entities from receiving any new commands 2. Let the sharded entities finish their work 3. Actually shut down the ShardRegion, stopping all sharded entities and allowing other shards to start this shard's entities To give some context, in my case command processing involves some interaction between sharded entities and other actors (e.g. updating an ElasticSearch index), so step 2 involves more than just stopping the sharded entity actor. This looks like a common problem, but I found no API for doing step 1 without stopping sharded entity actors. In particular, sending GracefulShutdown to the ShardRegion appears to do 1. and 3. without allowing the application code to do 2. Am I missing something? Any help is appreciated. - Arno -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
