             Summary: Abstract SlotPool from JobManager by introducing SlotPoolService
                 Key: FLINK-21077
                 URL: https://issues.apache.org/jira/browse/FLINK-21077
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.13.0
            Reporter: Till Rohrmann
             Fix For: 1.13.0


In order to support different slot pools in the {{JobMaster}}, I propose to introduce a {{SlotPoolService}} which is used by the {{JobMaster}} to manage different slot pool types. Additionally, this service allows to retrieve the encapsulated slot pool given the correct type. This will be helpful in order to use the {{DeclarativeSlotPool}} instead of the {{DefaultSlotPool}} when using the declarative scheduler.
