Is it possible to run the initial sync for Mailchimp -&gt; BigQuery on Open Source and then have Airbyte Cloud handle the daily updates in the same dataset?

Hmm, I don't know enough to give you a confident answer yet. However, you can refer to the Airbyte documentation for more information on [Mailchimp](<https://docs.airbyte.com/integrations/sources/mailchimp>) and [BigQuery](<https://docs.airbyte.com/integrations/destinations/bigquery>). If you have further questions, feel free to join the [Airbyte Slack](<https://airbytehq.slack.com/ssb/redirect>) and ask in the appropriate channels.

Hello Simon, any particular reason to run this strategy?

My initial sync would cost me around 500 euro’s worth of tokens. I could just run the sync on open source and get the same results for free
