Chetan Mehrotra commented on OAK-2627:
--------------------------------------

bq. Off Topic: Is getReference() part of the DataStore API and 
getContentIdentity() is its equivalent on the JCR level Jackrabbit API? Then 
the latter would just expose the same information to a higher level that is 
accessible by applications.

[getReference|https://docs.adobe.com/docs/en/cq/5-6-1/javadoc/org/apache/jackrabbit/api/ReferenceBinary.html]
 implementation basically rely on 
[getContentIdentity|http://jackrabbit.apache.org/api/2.0/org/apache/jackrabbit/api/JackrabbitValue.html].
 Using the identity as a seed then create an encrypted value which can then be 
trusted by target system.

> During some work on the upgrade tool, I discovered tat AbstractBlob's 
> {{equals}} method does not leverage reference comparison.
> While I have not investigated whether this really helps, I suspect it does. 
> This issue is for the consideration of people with a deeper understanding of 
> the system's dynamics.
