Cassandra journal persistence - query on parallelism across persistenceIds

[Muthukumaran Kothandaraman]

Hi, 

I would like to understand the possible degree of parallelism in Cassandra persistence plugin with Cassandra 3.4.0. 

For my usecase, I would be having around 3K distinct peristent actors using event-sourced pattern with Akka 2.4.1. I am not using any other capabilities like sharding. But 3K actors would be spread across akka cluster nodes - all cconnecting to Cassandra cluster for persistence. 

I assume events persisted across different persistenceIds can go in parallel so that overall event-persistence throughput across actors is better. Is Cassandra persistence plugin implemented this way ? Any specific configurations I have to be aware of except for possible persistence dispatcher tuning ?

Regards

Muthu

That is correct
