[GitHub] [arrow-datafusion] liukun4515 opened a new issue, #2831: Optimization InList: compare the float data type using OrderedFloat
liukun4515 opened a new issue, #2831:
URL: https://github.com/apache/arrow-datafusion/issues/2831
Elsewhere in DataFusion (including in `ScalarValue`) we use `ordered_float` to compare floating point numbers
It might be possible to use `set::<OrderedFloat<f32>>`, which would be more space efficient (fewer bytes than `ScalarValue`) as well as faster (as the comparison doens't have to dispatch on the type each time)
