> Filter pushdown could be improved. Based on my experiments there's no
> reasonable way to do it with DN 2.0, due to DN bug in substring and
> Collection.get(int) not being implemented.
> With version as low as 2.1 we can use values.get on partition to extract
> values to compare to. Type compatibility is an issue, but is easy for strings
> and integral values.
