I'm trying to delete records in my target table based on whether the records exists in the source table. I tried using the 'Delete' step but then realized that this step is based on a conditional clause.
My condition is quite simple "if the record/row DOES NOT exist in table A [source] delete the record/row from table B [target]".
I also read about using the the 'Merge Rows (diff)' step, but that seems to scan/compare the entire set of tables for differences.
The table is several million records with many hundred columns on a MySQL server, I need to perform this in the most efficient manner.
Any help would be appreciated.
