Connector Feature Support

Composer queries each connector to better understand its data store's capabilities and behavior. The connector's response describes to Composer the Composer features that the connector and the data store can support and any limitations to that support. It identifies the type of data requests that the connector and its data store can fulfill.

To learn more about a Composer feature and the connectors that support it, select the feature from the list below, organized by feature category:
