This is the approach I use with a different database which basically can only do bulk loads, because single INSERTs are very slow. The approach is:

  1. Read input data using Text::CSV_XS
  2. Perform cleanup on each row
  3. Add relevant columns (source_file, source_date)
  4. Write output TSV file in the correct encoding (Text::CSV_XS, this time writing tab-separated output)
  5. Issue bulk load statement
  6. Check that the number of rows read in 1, written in 4 and retrieved from the database are as expected
