In an environment where not all operations are run in an automated fashion, where new data sources are to be integrated, or where existing ETL processes are to be changed, we recommend that you set an error logging limit to prevent accumulation of too many malformed rows in the error logging tables. If malformed data rows need to be inspected, we recommend that you use a custom error logging table, or, if you are on a system running Aster Execution Engine, specify a unique or meaningful label for each load.
