Support for the Salesforce Bulk API 2.0 is now Generally Available in the Salesforce (Actions) destination.
With this new functionality, customers can opt to send data to Salesforce in batches of up to 1000 events. By default, the Salesforce (Actions) destination will continue to send data to the Salesforce streaming REST API, but customers can choose to use the Bulk API 2.0 instead.
For more information, see Segment's Salesforce (Actions) Destination documentation.
