>
> When a table is created with a partition by clause, the parquet writer will
> create separate files for the different partition values. The data will first
> be sorted by the partition keys, and the parquet writer will create new file
> when it encounters a new value for the partition columns.
> When data is queried against the data that was created this way, partition
> pruning will work if the filter contains a partition column. And unlike
> directory based partitioning, no view is required, nor is it necessary to
> reference the dir* column names.
