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

             Summary: Expose batch slot request via new scheduling mode
                 Key: FLINK-13187
                 URL: https://issues.apache.org/jira/browse/FLINK-13187
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.9.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.9.0


In order to leverage the newly introduced batch slot request feature introduced with FLINK-13166, we should introduce a new {{ScheduleMode#LAZY_FROM_SOURCES_WITH_BATCH_SLOT_REQUESTS}}. Users who enable this, must make sure that the generated job does not contain any pipelined shuffles because this can lead to resource deadlocks (not timing out requests with too few slots to make a pipelined region run).
