Awesome tooling, great to see some open source work in this space. How do you handle Testing/Data Reconciliation with Airbyte? How do I know if I have successfully transferred 100/100 records for the day? Is there a pattern that you can recommend here or a batch row count id that is recorded that can be queried against the source for confirmation that the correct amount of rows were added for x batch?
