Class FairsharePolicy

    • Method Detail

      • shareDecaySeconds

        public final Integer shareDecaySeconds()

        The amount of time (in seconds) to use to calculate a fair share percentage for each fair share identifier in use. A value of zero (0) indicates the default minimum time window (600 seconds). The maximum supported value is 604800 (1 week).

        The decay allows for more recently run jobs to have more weight than jobs that ran earlier. Consider adjusting this number if you have jobs that (on average) run longer than ten minutes, or a large difference in job count or job run times between share identifiers, and the allocation of resources doesn’t meet your needs.

        Returns:

      • computeReservation

        public final Integer computeReservation()

        A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.

        The reserved ratio is (computeReservation/100)^ActiveFairShares where ActiveFairShares is the number of active fair share identifiers.

        For example, a computeReservation value of 50 indicates that Batch reserves 50% of the maximum available vCPU if there's only one fair share identifier. It reserves 25% if there are two fair share identifiers. It reserves 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there's only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.

        The minimum value is 0 and the maximum value is 99.

        Returns:
        A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.

      • hasShareDistribution

        public final boolean hasShareDistribution()
        For responses, this returns true if the service returned a value for the ShareDistribution property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • shareDistribution

        public final List<ShareAttributes> shareDistribution()

        An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasShareDistribution() method.

        Returns:
        An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0.

      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object

      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
