When Airbyte detects a change in your source schema, it gives you the option to reset the affected streams. This is recommended because a reset will delete data in the destination of the affected streams and then re-sync that data. Skipping a reset might lead to unexpected behavior [source](
https://docs.airbyte.com/cloud/managing-airbyte-cloud/configuring-connections). However, if you want Airbyte to automatically propagate changes, you can configure it to do so. You can specify for each connection how Airbyte should handle any change of schema in the source. The options include: -
Propagate all changes: automatically propagates stream changes (additions or deletions) or column changes (additions or deletions) detected in the source -
Propagate column changes only: automatically propagates column changes detected in the source -
Ignore: any schema change, in which case the schema you’ve set up will not change even if the source schema changes until you approve the changes manually -
Pause connection: disables the connection from syncing further once a change is detected [source](
https://docs.airbyte.com/cloud/managing-airbyte-cloud/manage-schema-changes). To review non-breaking schema changes, follow these steps: 1. On the [Airbyte Cloud](
http://cloud.airbyte.com/) dashboard, click
Connections and select the connection with non-breaking changes (indicated by a
yellow exclamation mark icon). 2. Click
Review changes. 3. The
Refreshed source schema dialog displays the changes detected. 4. Review the changes and click
OK to close the dialog. 5. Scroll to the bottom of the page and click
Save changes [source](
https://docs.airbyte.com/cloud/managing-airbyte-cloud/manage-schema-changes). If you're still having issues, it might be helpful to provide more details about your setup, such as your Airbyte version and connectors.
