How We Improved Scheduler Performance for Large-scale Jobs …

Job Manager does not send the execution graph. In my opinion, the Execution graph is the logical view of the execution of the tasks (i.e. parallel instances of an operator-chain aka Task, slot-sharing group of tasks). JobManager searches for available task-slots to allocate to slot-sharing groups. WebWith StreamGraph, Flink Runtime will further translate it into JobGraph. The difference between JobGraph and StreamGraph is that JobGraph will chain some nodes to form an Operator chain. The chain condition requires the concurrency of the two operators to be the same, and their data exchange method is one-to-one. WebThe JobGraph represents a Flink dataflow program, at the low level that the JobManager accepts. All programs from higher level APIs are transformed into JobGraphs.
