Slow execution times and too much debug output #22

Closed setzer22 closed 6 years ago

setzer22 commented 7 years ago

Hello all,

I don't know if this is a current issue with the application or I just haven't found the feature. When mapping a JSON (an array of several hundred values) using RML-Mapper, I get very slow execution times and a lot of debug information is printed on the terminal. From that, I get the impression the tool is running in debug mode, is there a way I could use a more optimized mode that omits all the debug information for each mapped triple and, hopefully, runs faster?

Right now I see the tool mapping around 5 JSON objects per second. I think I'm probably doing something wrong. If there is a feature for this, I would suggest for it to be added more clearly in the README documentation. Otherwise I think there should be a way to disable all that debug output.

Thank you for your help!

Hi,

We've updated the RMLMapper and it can now be found here. Now debug output is disabled by default and can be enabled via -v and the overall execution should be faster. If you have still issues, you can open a new issue at the repo of the new RMLMapper.
