Match Only Previous Rowid Objects

Match Only Previous Rowid Objects

Enable this property to match the current records against records with lower ROWID_OBJECT values.
For example, if the current record has a ROWID_OBJECT value of 100, then the record is matched only against other records in the base object with a ROWID_OBJECT value that is less than 100. Records that have a ROWID_OBJECT value that is higher than 100 are ignored during the match process.
Use the Match Only Previous Rowid Objects property to reduce the number of matches required and speed performance. However, if you run PUT API calls, or if records are inserted out of rowid order, then records might not be fully matched. You must assess the trade-off between performance and match quantity based on the characteristics of the data and your particular match requirements.
You can enable the Match Only Previous Rowid Objects property to improve the performance of initial data loads. You might lose potential matches if you enable this property for incremental data loads. By default, this option is disabled.
