Alexander Kolbasov commented on HIVE-15373:
-------------------------------------------
I see, makes sense. Is there a specific reason not to create persistence
manager per transaction which then should take care of nested transactions
(which should create their own persistence manager and open transaction within
its context)?
> DbNotificationListener should use thread-local RawStore

> ObjectStore.java has several important calls which are not thread-safe:
> * openTransaction()
> * commitTransaction()
> * rollbackTransaction()
> These should be made thread-safe.
