@Kaniz Fatma​ , Thanks, that helps. I was assuming this warning indicated a schema evolution, and based on what you say it likely wasn't and I just have to turn on IgnoreChanges any time I have a stream from a table that receives updates/upserts.

To be clear though, in such a case turning on IgnoreChanges would not prevent errors if I ever have a schema evolution, correct? I would still get a notification of such a change? Or will turning on IgnoreChanges mean I fail to get alerts on that also?
