    +*********************************
    +Define Partition Table
    +*********************************
    +
    +Tajo makes it easy to specify an automatic partition scheme when the table 
is created.
    +
    +================================================
    +How to Create Partitione Table
    +================================================
    +
    +You can create a partitioned table by using the ``PARTITION BY`` clause. 
For a column partitioned table, you should use
    +the ``PARTITION BY COLUMN`` clause with partition keys.
    +
    +For example, assume there is a table ``student`` composed of the following 
schema.
    +
    +.. code-block:: sql
    +
    +  id     INT,
    +  name   TEXT,
    +  grade  TEXT
    +
    +Now you want to partition on country. Your Tajo definition would be this:
    +
    +.. code-block:: sql
    +
    +  CREATE TABLE student (
    +    id     INT,
    +    name   TEXT,
    +    grade  TEXT
    +  ) PARTITION BY COLUMN (country TEXT);
    +
    +Now your users will still query on ``WHERE country = '...'`` but the 2nd 
column will be the original values.
    +Here's an example statement to create a table:
    +
    +.. code-block:: sql
    +
    +  CREATE TABLE student (
    +    id     INT,
    +    name   TEXT,
    +    grade  TEXT
    +  ) USING PARQUET
    +  PARTITION BY COLUMN (country TEXT, city TEXT);
    +
    +The statement above creates the student table with id, name, grade. The 
table is also partitioned and data is stored in parquet files.

    Is 'parquet files' right?
