[Thanks, Gonzalo. That's the part I'd underline too. The poller was what I had optimized, but the database was what showed up on the bill. In Fabric the only lever was the idle gap: the database pauses after 15 quiet minutes, so the fix was removing every touch, including one forgotten browser tab. The RDS seven-day auto-restart is a good one to add to that list.](https://hashnode.com/posts/fabric-sql-database-dispatcher-cost/6aedc64be2fbd4f7aef5abf6/comment/6aef563921f7eca6e70a5956#reply-6af207a531d9633afef5ece9)
