Description
This epic tracks the redesign of scheduling in Flink. Scheduling is currently a concern that is scattered across different components, mainly the ExecutionGraph/Execution and the SlotPool. Scheduling also happens only on the granularity of individual tasks, which make holistic scheduling strategies hard to implement. In this epic we aim to introduce a dedicated Scheduler component that can support use-case like auto-scaling, local-recovery, and resource optimized batch.
The design for this feature is developed here: https://docs.google.com/document/d/1q7NOqt05HIN-PlKEEPB36JiuU1Iu9fnxxVGJzylhsxU/edit?usp=sharing
