COPY ignoring extra columns

0

I recently noticed that Redshift COPY command is ignoring any extra columns at the end of the source file which are missing in the table being loaded. I remember copy command used to fail with Extra columns found error earlier. Is this a new behavior recently released?

Hello,

As per https://docs.aws.amazon.com/redshift/latest/dg/r_COPY.html , there has been no change to COPY command recently.

If you use COPY command with "maxerror" parameter then it will ignore the records with additional columns.

Thank You !
