---------------------------------
    Attachment: OAK-2572.patch

[patch|^OAK-2572.patch] for the same. It introduces a new {{CacheInvalidationStats}} interface to wrap invalidation result and make {{DocumentStore#invalidateCache}} return that. For now only {{MongoDocumentStore}} return the stats and other return null

> Currently {{DocumentNodeStore}} logs at info level some stats when the background operation takes more than 10 sec. In many cases it is seen that time is spent in read but we do not get any insight around where it is spent. 
> As one of the major work of backgroundRead is to invalidate cache it would be good to include the cache stats
