> Performance tests on SAI have shown that the number of rows being filtered
> for wide row partitions is more than expected. For a 10k row/partition test -
> limit 10, the following has been observed.
> !image-2023-08-08-13-49-19-576.png|width=952,height=368!
> This is not the expected outcome of row-awareness and needs investigating.
> The number of rows read should, roughly, match the number of partitions read.
