@amansinha100 I have removed the override of `getMaxRowCount` method of
`TableScan` type to avoid your worry about unexpected results . This PR's
target adjusts to just enhance the current cartesian join by leveraging
Calcite's `RelMdMaxRowCount` method. I will solve our case specially at our env.---
