{
  "cluster_id": "string",
  "segment_host_count": "int64",
  "add_segments_per_host_count": "int64",
  "duration": "int64",
  "parallel": "int64",
  "close_cluster": "bool",
  "delay_redistribution": "bool"
}

Field	Description
cluster_id	string Required field. ID of the Greenplum Cluster resource to update. To get the Greenplum cluster ID, use a ClusterService.List request. The maximum string length in characters is 50.
segment_host_count	int64 Number of hosts for add to the segment subcluster
add_segments_per_host_count	int64 Number of segments per host to add
duration	int64 Redistribute duration, in seconds
parallel	int64 Redistribute process parallelism, 0 - for automatic detection
close_cluster	bool Deny all client connections during the expand operation
delay_redistribution	bool Perform redistribution process by small chunks as background activity

}

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
created_at	google.protobuf.Timestamp Creation timestamp.
created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	google.protobuf.Any Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	google.protobuf.Any The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
