Subject [jira] [Commented] (OAK-2973) [Blob GC] Report accurate deleted count
Date Wed, 05 Aug 2015 05:28:04 GMT

Chetan Mehrotra commented on OAK-2973:
--------------------------------------

Change looks fine. 

However bumping major version might pose a problem. May be we should mark the {{MarkAndSweekGarbageCollector}}
with provider type. However it might still result in major version change as return type is
being changed. Worst case we might need to provide a new method and let old method delegate
to that (in AsbtractBlobStore) and make use of new method

> Currently, the underlying data stores do not report the actual count deleted from the
candidate set in the {{GarbageCollectableBlobStore#deleteChunks}} method as there may be blobs
not satisfying the max last modified criteria. 
> For debugging it would be better to support returning the actual deleted count so that
{{MarkSweepGarbageCollector}} can accurately report the count of blobs deleted.
