@larvinloy you can use the last approach I’ve shared on that topic. use literal numbers instead of Blank Node.
About your ask, it is a pretty huge change in the Liveloader. Not sure if you gonna see this done as fast as you need.
The Liveloader or Bulkloader have strong logic with RDF/JSON. It would be hard to introduce a new player (a query) in this context. It is impossible to add query logic in RDF or JSON. I can’t see an easy way that this having some overall compliance with RDF/JSON.
We would have a logic that reads your RDF and separate the batches in small pieces to use in a transaction batch. But It is hard to code predict what the users want. Things can go out of control fast.
But nothing is impossible with hard work to change the whole thing.
For sure your load would not be pure RDF. You would have to change all your RDF to the Upsert block format. This requires manual work on your side. Or create some script that converts your RDF to Upsert Block.
