> For filesystem partitioning, we want to use the existing directory structure
> of the data. So, if a selection is a directory that contains subdirectories,
> the name of the directory a given record was stored in can be included as a
> field in that record. For example, given this structure:
> /data
> /a
> file.csv
> /b
> file.csv
> select * from dfs.`/data`
> will include a column named dir0, with possible values a and b. This can be
> extended to a hierarchy of partitions. For example,
> /data
> /a
> /1
> file.csv
> /2
> file.csv
> /b
> file.csv
> would have columns dir0 (with possible values a and b) and dir1 (with
> possible values 1, 2 and null).
> The data type will always be VARCHAR for the partition columns.
