KNIME Constraints and Restrictions

I have downloaded the KNIME Analytics Platform and I am having issues with it reading a CSV file that represents my input data file.  The input data file has over 2 million columns and over 25,000 rows.  I have tried numerous times to get the file reader to ingest this file, but the reader only recognizes 1 column.

Does KNIME have any restrictions on the number of columns that are in a CSV file?



Two million columns are certainly too many. The number of rows is unlimited, but the number of columns shouldn't get much larger than ~10.000. In case all your columns have the same type, you may want to have a look at the "KNIME Nodes for Wide Data" extension. It allows to read all columns into a single "array" columns.
