Waiting for confirmation from the SMEs

Temp solution in MODSOURCE-530: error the second copy of the record and do not process. What is the desired behavior for the SMEs?

Duplicate record = 2 or more MARC Bibs that will match to the same Instance

If file contains duplicate records - DI should log them as errored and prevent further processing.

New mechanism should be added in SRM. After incoming record is parsed - check (by 001 value) if such record has already been parsed for a particular job execution. To do that - add table to store 001 values and job execution id, add composite constraint on both values, try saving new value - if save is successful then proceed as usual, if db throws constraint violation error - throw DI_ERROR with message "Incoming record is a duplicate of <001> record". When job is marked COMPLETED - delete rows from that table by job execution id.

Add tests.
