> Components: C++
> Reporter: Wes McKinney

>
> The current implementation of {{Filter}} on RecordBatch, Table does redundant
> analysis of the filter array. It would be more efficient in most cases (i.e.
> whenever there are multiple columns) to convert the boolean array into a
> selection vector and then use {{Take}}
