About this task When you prepare to delete many records from a table, consider the following guidelines to minimize impact on performance. Limit the number of records to be deleted in a single delete action to prevent the table from being locked. Use the setLimit() method described at setLimit. Minimize triggering an excessive number of business rules as a result of this deletion. Use the setWorkflow(Boolean e) method described at setWorkflow.
