> 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).
