> 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.
