Why Data Load Performance Decreases due to Bad Records?

Question

Why data load performance decreases due to bad records?

Answer

If bad records are present in the data and BAD_RECORDS_LOGGER_ENABLE is true or BAD_RECORDS_ACTION is redirect then load performance will decrease due to extra I/O for writing failure reason in log file or redirecting the records to raw CSV.
