trait Partitioning extends AnyRef
An interface to represent the output data partitioning for a data source, which is returned by
SupportsReportPartitioning#outputPartitioning().
Note: implementors should NOT directly implement this interface. Instead, they should use one of the following subclasses:
- Annotations
- @Evolving()
- Source
- Partitioning.java
