Reflection Too Expensive

I have a reflection on a VDS that is a small data set and queries very quickly (<1s). However, when I write a query that uses that VDS, it does not get accelerated and The Acceleration tabs states that the Raw Reflection is Too Expensive. I’m not entirely sure what that means or why it’s not selected. Has anyone had experience with this?

Hi @summersmd

I just replied via Reflected data sources not chosen? why we sometimes match and not pick the reflection.
