Implement statistics estimation for FilterExec #3845
Description
Is your feature request related to a problem or challenge? Please describe what you are trying to do.
@isidentical implemented more statistics-rules for joins. When a FilterExec is between a TableScan however, we do not return a join estimation yet.
Describe the solution you'd like
We should provide an estimation based on the filterexpressions and statistics information that we have.
Describe alternatives you've considered

Awesome @isidentical I assigned you on this issue!

I would be very interested to see if we're getting any changes in TCP-H queries after this.

Will be sure to include some benchmarks 👍🏻

@Dandandan I see there are couple of stats related issues opening, is there an umbrella task/task lists? Or maybe we can tag all related issue as CBOStats ?

I think @isidentical started a discussion on #3898 -- @mingmwang could you take a look? Perhaps it would be time to start socializing that ticket more broadly (I could send some email / slack messages to bring it to the community's attention)

@alamb Thanks, I will go through all the tickets and take a closer look at the current code base , I can help working on some
of the open tasks.
