I want to conform whether itemUpdate can be limited for client to receive only UPDATE and DELETE event, since in my case the items for in ADD has no Data other than item Key since our application has lot of Items to be ADDed we are finding ways to ignore it. can you please suggest is that an expected behavior or we can do some work around to limit the item updates using selector or something else..

I am using two adapters
1. INIT Adapter- To ADD/remove a record from External source say DB
2. DATA Adapter - To publish actual Data fields
