@kapa.ai does the "Refresh your data" feature create any data downtime while the data is refreshed from the old copy to the new copy?

No, the "Refresh your data" feature in Airbyte does not create data downtime while the data is refreshed. According to the documentation: "Refresh Syncs do not create data downtime. While the Refresh Sync is running, the previous data in your destination remains available to query. Only at the successful conclusion of a Refresh Sync will the newly refreshed data be swapped or merged into place." [Airbyte Documentation](https://docs.airbyte.com/operator-guides/refreshes#overview) specifically mentions that this is an improvement over the previous "Reset Syncs" that Airbyte had in earlier versions. For certified database and data warehouse destinations, Airbyte accomplishes this by writing to a temporary location during the sync, and then swapping the tables at the end: "This allows us leave the previous sync's data viewable by writing to a "final-table-tmp" location as the sync is running, and at the end dropping the old "final" table, and renaming the new one into place." [Airbyte Documentation](https://docs.airbyte.com/using-airbyte/core-concepts/sync-modes/full-refresh-overwrite#destination-specific-mechanism-for-full-refresh) This approach ensures that users have continuous access to their data throughout the refresh process, minimizing disruption to data availability.
