data |
array
Optional. Data for populating the Message object. |
↳ min_instances |
int
Optional. Minimum number of instances for this group. Primary workers - Bounds: [2, max_instances]. Default: 2. Secondary workers - Bounds: [0, max_instances]. Default: 0. |
↳ max_instances |
int
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. |
↳ weight |
int
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 |

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.

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.

secondary worker.
The cluster may not reach the specified balance if constrained
