A partition is composed of a subset of rows in a table that share the same value for a predefined subset of columns called the partitioning columns.

Using partitions can speed up queries against the table as well as data manipulation.

To use partitions, you define the set of partitioning column when you create a table by including the PARTITIONED BY clause.

When inserting or manipulating rows in a table Data bricks SQL automatically dispatches rows into the appropriate partitions.
