>             Project: Calcite
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 1.34.0
>            Reporter: Adam Kennedy
>            Priority: Minor
>   Original Estimate: 1h
>  Remaining Estimate: 1h

> A few locations in Calcite call rel.estimateRowCount(mq) when they should instead call mq.getRowCount(red).
> We detected this because we implemented row count estimation entirely within an alternative handle instead of RelMdRowCount, and then override estimateRowCount to ensure the custom handler is user, by throwing an unreachable code exception.
> A few places in Calcite trigger these unreachable exceptions because they do not use mq.getRowCount.
