Configuring the Data Loader to Use the Bulk API

Available in: Enterprise, Performance, Unlimited, Developer, and Database.com Editions

The Bulk API is optimized to load or delete a large number of records asynchronously. It is faster than the SOAP-based API due to parallel processing and fewer network round-trips. By default, Data Loader uses the SOAP-based API to process records.

To configure Data Loader to use the Bulk API for inserting, updating, upserting, deleting, and hard deleting records:

  1. Start Data Loader by choosing Start | Programs | Salesforce | Data Loader | Data Loader.
  2. Choose Settings | Settings.
  3. Select the Use Bulk API option.
  4. Click OK.
  • You can also select the Enable serial mode for Bulk API option. Processing in parallel can cause database contention. When this is severe, the load may fail. Using serial mode guarantees that batches are processed one at a time. Note that using this option may significantly increase the processing time for a load.
  • Caution: When you select the Hard Delete operation, the deleted records are not stored in the Recycle Bin. Instead, they become immediately eligible for deletion.
