We have a need to use REST nodes for populating into a database (triple store).
We want to put a large block of data (several million triples) as a block through the “body” of a PUT or POST request.
We have tried to do this by using a group by node to concatenate the rows of a single column table (the entry in each cell is a triple), and to put either by specifying the request body column or by converting to a flow variable and assign to a constant body.
In both cases it fails when we join a large number of rows together.
Is there a way to have the REST node take a table into the body as one call, without making separate calls for each row?
