How does KNIME handle CSV files of ~2GB?

Dear KNIME Support Team,

When I try to read a ~2GB CSV file directly in KNIME 5.4.4, I get the following error:

Execute failed: Memory limit per column exceeded.
Please adapt the according setting.

To work around this, I switched to the File Reader node and enabled:

Table specification → Limit data rows scanned = 10,000

While the node executes successfully, the actual output only contains 10,000 rows, so the full CSV data is not read.

If I disable the row limit, the memory error persists.

The JVM heap has been increased to -Xmx6144m, and the CSV contains multiple long String columns.

I would appreciate KNIME official support guidance on:

• How to handle such a large CSV file without upgrading KNIME?

• Recommended usage or configuration for File Reader / CSV Reader nodes?

• Reliable methods to ensure full reading of a ~2GB CSV file?

Thank you very much!
