The `BasicEnforcement` can choose to satisfy given ordering/partitioning requirements in different ways. For example a requirement ordering `['a'] `can be satisfied by sort by `['a']`, sort by` ['a', 'b']`, order by `['a', 'b', 'c']`, sort by `['a', random]` ...... In future, we will add support for Range Partitioning, if the optimizer detects the column a is a skewed column, it can effectively add sort by `[a + random()] `to avoid data skew in the Range Partitioning. -- This is an automated message from the Apache Git Service.
