| Field                                                  | Description                                                                                                                                                                                                |
| ------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Path to buffer the bulk job payloads**               | Specify the directory to store the temporary files. This location is also used to retrieve output records. The temporary files are automatically deleted when the step finishes.                           |
| **Maximum size of a buffered payload file (in bytes)** | Specify the maximum number of bytes to buffer and transmit in a bulk operation job. The maximum is the default 100 MB (104,857,600 bytes). If needed, you can lower this number to prevent locking errors. |
| **Buffer payload only (do not upload in job)**         | Add files to the directory specified in the **Path to buffer the bulk job payloads** field, but do not upload them to Salesforce.                                                                          |
| **Cleanup bulk jobs once processed**                   | Select to delete the buffer files when the step finishes.                                                                                                                                                  |
| **Salesforce API version**                             | Specify the Salesforce Bulk API version for your connection.                                                                                                                                               |
