> When using {{DROPMALFORMED}} mode, corrupted records aren't dropped if malformed columns aren't read. This behavior is due to CSV parser column pruning. Current doc of {{DROPMALFORMED}} doesn't mention the effect of column pruning. Users will be confused by the fact that {{DROPMALFORMED}} mode doesn't work as expected.
