When I use the `filter` kernel with Null strings, any input column that was Null turns into an empty string after filtering. ``` "foo" "bar" NULL ``` And the filter ``` true true true ``` Will result in ``` "foo" "bar" "" ``` Rather than ``` "foo" "bar" NULL ``` It appears to work fine for primitive arrays (I'll comment inline). I also added `BinaryArray::from_opt_vec` following the model of `PrimativeArray` and `StringArray` mostly so I could write a test. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
