• Use Change Data Capture to update downstream systems accordingly when a record changes.

• Locally cache external IDs at the middleware layer and design business logic to map updates between systems.

A company needs to be able to send data from Salesforce to a homegrown system behind a corporate firewall. The data needs to be pushed only one way and doesn't need to be sent in real time. The average volume is 2 million records per day. What should an integration architect consider when choosing the right option in building the integration between the external system and Salesforce?

• Due to high volume of records, number of concurrent requests can hit the limit for the REST API call to the external system.

• Due to high volume of records, the external system will need to use a BULK API Rest endpoint to connect to Salesforce.

• Due to high volume of records, a third-party integration tool is required to stage records off platform.
