Query Optimization
- Create a custom lowering transport for sampling queries.
- Add handlers for
- PhysScan
- Eval
- Filter
- Limit
- NLJ
- No use of cascades properties: will need to make use of FieldProjectionMap of sargable node.
- Use SBEExpressionLowering to lower expressions directly which hang off of Filter and Eval nodes.
- Add a node that counts on top (group)
- might be simpler to do during this lowering
