----------------------------------------

             Summary: Make StreamTask#triggerCheckpointAsync return void
                 Key: FLINK-22209
                 URL: https://issues.apache.org/jira/browse/FLINK-22209
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Task
            Reporter: Dawid Wysakowicz
             Fix For: 1.14.0


The return value of {{StreamTask#triggerCheckpointAsync}} is ignored in production code. We should remove it to decrease chances for confustion.

We must make sure we do not lose test coverage with it. A lot of tests depend on that return value.
