---------------------------------
Summary: Fix documentation for DataSetUtils.zipWithUniqueId()
Key: FLINK-3634
URL: https://issues.apache.org/jira/browse/FLINK-3634
Project: Flink
Issue Type: Improvement
Components: Documentation
Affects Versions: 1.1.0
Reporter: Greg Hogan
Assignee: Greg Hogan
Priority: Minor
Fix For: 1.1.0, 1.0.1
Under FLINK-2590 the assignment and testing of unique IDs was improved but the
documentation looks to still reference the old implementation.
With {{parallelism=1}} there is no difference between zipWithUniqueID and
zipWithIndex. With greater parallelism the results of zipWithUniqueID are
dependent on the partitioning.
The documentation should demonstrate a possible result that is different from
the incremental sequence of zipWithIndex while noting that results are
dependent on the parallelism and partitioning.
