------------------------------------
Summary: Attach a "reason" message to Singleton partitioning
Key: BEAM-11839
URL: https://issues.apache.org/jira/browse/BEAM-11839
Project: Beam
Issue Type: Improvement
Components: sdk-py-core
Reporter: Brian Hulette
Assignee: Brian Hulette
When Singleton partitioning is required, we should be able to attach a reason
to it so we can raise a helpful message to the user later, e.g.
{{partitionings.Singleton(reason="Only 'pearson' correlation can be computed in
a distributed manner, other methods require Singleton partitioning")}}
