How does Airbyte handle changes in replication start date?

[anteakar]

I am trying to backfill Universal Analytics data and send it to BigQuery. When I set a replication start date that is far in the past I get too many 503 errors (which I have noticed happen at random) which end up getting me blocked from the Universal Analytics API for 24h. To tackle this problem I want to get my data in increments, for example from 2018 to 2019, 2019 to 2020 etc., but the UA connector in Airbyte does not allow for a replication end date to be entered so any replication happens from the specified start date until the day the sync was started. To tackle this I tried to set the replication start date in the source to 2022, make the mode incremental append + dedupe and then after the sync is done go back to the source and change the start date to 2021. I was hoping that in this way I could backfill year by year. However, the connection does not seem to detect the date change in the source even when I update the source schema. Does anyone know how I could tackle this?
