Not able to single insert 10k rows with 20 column each to Redshift

[kaps1602]

I have around 2 million rows to be inserted to Redshift and each row has 20 columns.  I have configured number of rows per insert 10000 and commit every 10000. Job get failed with error : java.sql.SQLException: [Amazon](500310) Invalid operation: there is no parameter $-32768;. Exception trace mentioned at the end.

Than I reduced number of rows per insert  and commit every  to 1000. It started working fine, but will takes lots of time to insert 2 million record.

How shall I quickly insert my data to Redshift?

Exception in component tRedshiftOutput_1 (CSV_RemoveNewLineFromElement_CSV)
