Large csv input used with rmlmapper

[titoarrabal]

Hi! Im trying to use rmlmapper over my csv files (1.400.000 rows), but it doesnt give any output because it keeps thinking. Is there another rmlToRdf conversor which could make that job? Thank you!

RML streamer gives me an error, and I dont know how to solve it. I leave the error here! Exception in thread "main" java.util.NoSuchElementException: None.get at scala.None$.get(Option.scala:347) at scala.None$.get(Option.scala:345) at io.rml.framework.Main$.main(Main.scala:124) at io.rml.framework.Main.main(Main.scala)

Could you provide the mapping file and cli arguments you're using to try the rmlstreamer? It should be able to handle this amount of data :)

Hi! Did you try the standalone version of RMLStreamer? It looks like this is the version that has to be deployed on a Flink cluster.
