An architect must choose how the Heroku side writes back to Salesforce for a high-volume integration. Which statements should shape the decision? (Select two.)
選択肢
- Bidirectional synchronization writes back through the trigger log and can use the bulk path when the conditions are met, which suits sustained high volume.
- The reference-only wrapper is not a write-back mechanism for the org's own objects; it exposes Postgres tables to the org instead.
- Bidirectional synchronization can be limited to a subset of the records to reduce volume, and the subset is chosen with a filter on each mapping.
- The reference-only wrapper can be used in standard reports once it is enabled, and its rows can be filtered and grouped like any other object.
- Direct API calls from the app are the recommended path for sustained high volume because they bypass the trigger log and therefore avoid the polling interval that the synchronization applies before it sends the accumulated changes to the org.
