Amit Jain commented on OAK-6544:
--------------------------------

This has to be linked to the synchronization interval for the BlobTracker (The 
thing which caches the blob ids locally), where its frequency has to be less 
than the frequency here so that it can synchronize the deletes before the full 
scale GC takes place.


> Enable active blob deletion feature by default

> OAK-2808 allows for active deletion of blobs created by lucene indexing. 
> Currently, the feature is disabled by default. This task is to track enabling 
> it by default before doing stable release of the feature.
> About the default enabled value: I think default interval to purge blobs can 
> be 6 hours be default. (Note, the purge logic, anyway won't purge blobs which 
> were deleted in recent past... 'recent'=24hours \[configurable via jvm 
> param]).
