Cannot store example set --> too many columns
I have run into a technical issue on Rapidminer Server for which I can't find a solution.
After running a process on the RM server, I would like to store the example set in the server repository. However, I get the following error message:
Reason: Cannot store example set in database as es_13: java.sql.SQLException: Too many columns.
The example set I am trying to store has 1 row (i.e. 1 example) and 1519 attributes, of which all but one are numerical (mostly integers). I have no issues running the exact same process in RM Studio on my local machine and storing example sets with even more columns and rows on there.
I understand that I am somehow hitting the hard limit in terms of column number on the database, but I don't really know why, as data volume and types of the process should not cause these kind of issues.
The question is: is there anything I can do in terms of configuration so that this problem goes away without going through the trouble of spliting my process output?
Thank you very much for any hints in the right direction!
