Class LimitingScheduler

  • public class LimitingScheduler
extends java.lang.Object
    A scheduler that delegates to a ScheduledExecutorService while also enforcing a maximum upper bound of the amount of work that is being done. For our purposes, the amount of work corresponds to the number of telemetry items "in-flight" (being buffered) in memory.

    A call to schedule() will include a work unit "size" that is accumulated, and if the max would be exceeded then the work unit is rejected and a warning is logged.
