The Salesforce driver supports DataDirect Bulk Load, a feature that allows your application to send large numbers of rows of data to a Salesforce instance. The driver uses the Salesforce Bulk API for bulk load operations. You can specify which type of bulk load operation will be performed when a load method is called by setting the operation property using the setProperties() method of the DDBulkLoad interface. See Specifying the Bulk Load Operation.

In addition, you can configure the Salesforce driver to use the bulk load protocol when it encounters a request to execute a single Insert, Update, or Delete statement that affects multiple rows. See Using Bulk Load for Single Inserts/Updates/Deletes (Salesforce Driver).

The following table summarizes the connection properties that affect how bulk load works with the Salesforce driver.

Table 1. Summary: Bulk Load Properties for the Salesforce Driver
Property Description
BulkLoadAsync

Determines whether the driver treats bulk load operations as synchronous or asynchronous. The default is 0 (synchronous).
BulkLoadBatchSize Provides a suggestion to the driver for the number of rows to load to the database at a time when bulk loading data. The default is 10000.
BulkLoadConcurrencyMode Determines whether multiple batches associated with a bulk load operation are processed by Salesforce in parallel or one at a time. The default is parallel.
BulkLoadPollInterval Specifies the number of seconds the driver waits to request bulk operation status. This interval is used by the driver the first time it requests status and for all subsequent status requests. The default is 10 (seconds).
BulkLoadThreshold Sets a threshold (number of rows) that, if exceeded, signals the driver to use bulk load for insert, update, delete, or batch operations. The default is 4000 (rows).
EnableBulkLoad Specifies whether the driver can use the bulk load protocol for insert, update, delete, and batch operations. The default is false.
