>             Project: Apache Drill
>          Issue Type: Improvement

> Provide the Table and Partition information on parquet tables created by 
> Drill in INFORMATION_SCHEMA. This can be utilized by tools and users looking 
> to optimize Drill queries by referencing the table and partition metadata 
> from within Drill, as opposed to querying the parquet metadata underneath.
> Potentially extend INFORMATION_SCHEMA with an additional PARTITIONS table 
> similar to MySQL to provide information on column(s) used for partitioning.
