Subject [jira] [Commented] (GEODE-7079) NPE Upon Restart When Using Asynchronous Event Distribution & Conflation
Date Fri, 16 Aug 2019 17:49:00 GMT

GEODE-7079: Prevent NPE During Queue Conflation (#3911)

* GEODE-7079: Prevent NPE During Queue Conflation

- Added tests.
- Fixed minor warnings.
- Use the cached region name when doing conflation instead of the actual region so the processor
doesn't need to wait for the actual region to be fully initialized.

> The following combination of features cannot be safely configured when using pure Geode
Java API:
> * Replicated Region.
> * Serial Gateway Sender or Serial Asynchronous Event Queue.
> * Serial Gateway Sender / Serial Asynchronous Event Queue is Persistent.
> * Conflation is Enabled for the Serial Gateway Sender / Serial Asynchronous Event Queue.
> The problem is that, after a restart, events left-over in the persistent queue begin
processing before their source {{Region}} is instantiated, causing a {{NullPointerExceptions}}
while executing the conflation logic.
> The {{Region}} is only required because internally we need its name, but the name itself
is already stored within the actual event so it should be safe to replace {{gsEvent.getRegion().getFullPath()}}
by {{gsEvent.getRegionToConflate()}} or {{gsEvent.getRegionPath()}}.
