[jira] Created: (JCR-2686) Data store garbage collection: interrupt
mark
Data store garbage collection: interrupt mark
---------------------------------------------
Key: JCR-2686
URL: https://issues.apache.org/jira/browse/JCR-2686
Project: Jackrabbit Content Repository
Issue Type: Improvement
Affects Versions: 2.1.0
Reporter: Stephan Huttenhuis
It would be nice if the DataStore GarbageCollector can be interrupted during a mark. This allows applications that use JackRabbit to shutdown without having to wait for the mark to complete.

-----------------------------------------
Close only removes the oberservation listener and does not do what I want. I would like an option to interrupt the mark method (or more precisely the scanNodes and scanPersistenceManagers methods) during a scan, so that a garbage collect does not prevent jackrabbit from stopping

Could you check if calling close() does what you want?

We would like to interrupt the sweep phase. We have two large JackRabbit installations with the following characteristics:
An environment with about 9000 binary values (BINVAL) and 350.000 node bundles where garbage collection took about 4 minutes.
An environment with about 4000 binary values (BINVAL) and 400.000 node bundles where garbage collection took about 7 minutes.

Hi,
You are right. Looking at the code, I'm not sure if calling close() already interrupts the "mark" phase if isPersistenceManagerScan() is false (because close() logs out the session). But the persistence manager scan isn't stopped. It should be relatively easy to implement and test this feature.
The "sweep" phase can't be interrupted currently, but I guess that's not the problem? I don't know how long a "sweep" call takes, but I guess not that long (a few seconds at most?)
