Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Support queryMore by Using Server-Driven Paging by Using Server-Driven Paging

With server-driven paging, the external system controls the paging and ignores any batch boundaries or page sizes that are specified in queries. To enable server-driven paging, declare the QUERY_PAGINATION_SERVER_DRIVEN capability in your DataSource.Provider class.

When the returned DataSource.TableResult doesn’t contain the entire result set, the TableResult must provide a queryMoreToken value. The query token is an arbitrary string that we store temporarily. When we request the next batch of results, we pass the query token back to your custom adapter in the DataSource.QueryContext. Your Apex code must use that query token to determine which rows belong to the next batch of results.

When your custom adapter returns the final batch, it must not return a queryMoreToken value in the TableResult.

The Apex Connector Framework doesn't support server-driven pagination for list views.
