Hi @pgha ,
I took a quick look into the code of the SPARQL nodes.
1.
The SPARQL Insert node runs an INSERT DATA for each row individually. So this will take its time for a big table.
2.
What is the Error in this case?
3.
That is pretty strange as both the File Inserter and the Insert node use an update request. Did you use the same endpoint in both cases?
However, as the SPARQL File Inserter will read the File and trigger a INSERT DATA for ever triple individually I would not expect that to be any faster then the SPARQL Insert anyway.
