    • Method Detail

      • getMinInstances

        int getMinInstances()
         Optional. Minimum number of instances for this group.

 Primary workers - Bounds: [2, max_instances]. Default: 2.
 Secondary workers - Bounds: [0, max_instances]. Default: 0.
        int32 min_instances = 1 [(.google.api.field_behavior) = OPTIONAL];
        Returns:
        The minInstances.

      • getMaxInstances

        int getMaxInstances()
         Required. Maximum number of instances for this group. Required for primary
 workers. Note that by default, clusters will not use secondary workers.
 Required for secondary workers if the minimum secondary instances is set.

 Primary workers - Bounds: [min_instances, ).
 Secondary workers - Bounds: [min_instances, ). Default: 0.
        int32 max_instances = 2 [(.google.api.field_behavior) = REQUIRED];
        Returns:
        The maxInstances.

      • getWeight

        int getWeight()
         Optional. Weight for the instance group, which is used to determine the
 fraction of total workers in the cluster from this instance group.
 For example, if primary workers have weight 2, and secondary workers have
 weight 1, the cluster will have approximately 2 primary workers for each
 secondary worker.

 The cluster may not reach the specified balance if constrained
 by min/max bounds or other autoscaling settings. For example, if
 `max_instances` for secondary workers is 0, then only primary workers will
 be added. The cluster can also be out of balance when created.

 If weight is not set on any instance group, the cluster will default to
 equal weight for all groups: the cluster will attempt to maintain an equal
 number of workers in each group within the configured size bounds for each
 group. If weight is set for one group only, the cluster will default to
 zero weight on the unset group. For example if weight is set only on
 primary workers, the cluster will use primary workers only and no
 secondary workers.
        int32 weight = 3 [(.google.api.field_behavior) = OPTIONAL];
        Returns:
        The weight.
