Is there any progress indicator available through the cloud API?

Yes, Airbyte has introduced throughput metrics and a progress bar to the Connection Sync History UI for Airbyte Open Source. These provide real-time information on data transfer rates and sync progress. However, the extracts do not provide specific information about the availability of these features through the Airbyte Cloud API. For more details, you can refer to the [release notes](https://docs.airbyte.com/release_notes/december_2022) or the [Airbyte Cloud API documentation](http://reference.airbyte.com/).
