> DataFrame reads attempt to match user expectations by giving every element across all
> shards a unique index. This is done by embedding the filepath
> itself in the index, but this results in the (often quite long) path
> being duplicated for every element (sometimes exceeding the size of the
> data itself).
> We should instead generate a guaranteed unique _numeric_ index.
