Do I use the same key-value storage (RockDBs) in 2 different StreamTask same time?

Question

I use Apache as Samza framework for Kafka and I need to share the same RockDBs key-value storage between 2 Tasks.

Is what I can do so without having concurrency on storage Key value?

I deployed 2 Tasks with same Key-value storage and it's working.

So yes we can.

As of Samza 0.12.0 there is no supported way of sharing stores between tasks. Each store is instantiated (isolated) for each task.
