Large csv input used with rmlmapper
titoarrabal opened this issue · 6 comments
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!

I am using yarrrml-paser to obtain map1.rml.ttl. Then, i use this command:
java -jar rmlstreamer.jar toFile --mapping-file C:/Users/Usuario/Desktop/TFG/Mapping/ComunidadMadrid/Meteorologicos/map1.rml.ttl --output-path prueba.nt
It gives me this error
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.
