Resolved! Incremental updates in Delta Live Tables
What happens if we change the logic for the delta live tables and we do an incremental update. Does the table get reset (refresh) automatically or would it only apply the logic to new incoming data? would we have to trigger a reset in this case?

Here is my finding on when to refresh (reset) the table: If it is a complete table all the changes would be apply automatically. If the table is incremental table, you need to do a manually reset (full refresh).
