In Airbyte, there is no specific configuration just to replicate the schema (structure) of tables without data, but you can use an approach to ensure that empty tables are still replicated with their structures. But my target is parquet and not another sgdb.

Airbyte does not directly support the replication of just the schema (structure) of tables without data. When Airbyte ingests data from the source (tables, views, materialized views, source APIs), it converts the data to the AirbyteMessage format and emits them to your destination. It doesn't duplicate the artifacts (tables, views, functions) of your database and recreate them in your destination. This allows Airbyte to connect any source to any destination, but it loses some features like the option to recreate the source database in your destination [[source]](https://discuss.airbyte.io/t/459). However, if you're using a source that does not support namespaces, the data will be replicated into the destination's default namespace. If the destination does not support namespaces, any preference set in the connection is ignored [[source]](https://docs.airbyte.com/using-airbyte/core-concepts/namespaces#examples). As for your target being Parquet, Airbyte currently does not support Parquet as a destination. The available destinations are mostly databases and data warehouses, and the data is typically stored in tables within these destinations. You can check the list of available destinations in the Airbyte documentation. If you want to replicate just the schema without data, you might need to create a custom connector or use a workaround outside of Airbyte. Please note that this might not be the best practice and could lead to unexpected results or issues.
