Marcel Reutegger commented on OAK-3878:
---------------------------------------

My preference is also an explicit flag in the query method.

> Avoid caching of NodeDocument while iterating in BlobReferenceIterator

> {{BlobReferenceIterator}} in DocumentMK makes use of {{DocumentStore}} API to 
> query the NodeDocument. This would cause all those NodeDocuments to be added 
> to cache in DocumentStore. Due to this when blob gc is running cache usage 
> would not be that effective due to all the associated churn. 
> As these NodeDocument are only required for BlobGC logic and its not expected 
> that this document would read again soon it would be better to skip caching 
> of these documents within DocumentStore
> Similar requirement exist in VersionGC logic but there we use direct store 
> based API which does not add such documents to the cache
