Alexander Klimetschek commented on OAK-8552:
--------------------------------------------

[~amitjain] I don’t think [~ianeboston] was suggesting to use the 
jcr:lastModified JCR property for that. All of these could be internal fields 
not exposed on the JCR level.

With direct binary access we also no longer support de-duplication (too 
costly), so that aspect can be ignored for binaries uploaded that way or if a 
corresponding configuration is set. But there is still copying/versioning of 
nodes which leads to multiple references to the same blob - does this lead to a 
last modified update of the blob? (Just curious because I wasn’t aware of that)

Nonetheless, for the issue at hand I don’t think we need to change anything 
stored in the NodeStore. The size/length is already stored in the NS as part of 
the internal blob id.
