| Parameter Name         | Default Setting | Required | Description                                                                                                                                                                                                                                                           |
| ---------------------- | --------------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Destination Batch Size | 100             | No       | Limits the number of rows that will be written to the target database in a single batch. A smaller number minimizes memory requirements but increases run time. A larger value increases memory requirements and decreases run time.                                  |
| DDL Timeout (seconds)  | Blank           | No       | Set the number of seconds CopyStorm will wait for a DDL operation to complete. DDL operations, like CREATE INDEX, may take considerably longer than DML operations and thus have their own timeout parameter.                                                         |
| # Database Buffers     | 10              | No       | Sets the number of output buffers to use when running in multi-thread mode. A larger value increases memory requirements but allows Salesforce to read more records before they are written to the target database.                                                   |
| Rows Per Multi-Insert  | Blank           | No       | If specified then multiple rows will be sent to the database in a single INSERT statement. Please note that not all databases support this feature and when the database is on a local network there is unlikely to be any performance gain by enabling this feature. |
| Enable CSV Bulk Import | Checked         | No       | If set and is supported by the database then CSV bulk imports will be used. For analytical databases like RedShift or Snowflake this option should almost always be selected.                                                                                         |
