Thanks Chetan, for the helpful info.
Yes you are correct I am talking about MongoBlobStore here.
I tried to find out the reference by using following query
db.nodes.find({blobId:{$exists:true}}. It returns nothing. Can you please
point me to the query I need to use to see the reference at work
My higher level objective is to understand , how Data is stored in Mongo DB
from say a page. When an user create a page and add some contents to it I
understand different nodes are getting created; but what exactly is driving
storing data in blob and interaction between node and blobs collection

Abhijit
