ExpandRequest

clusterId : string

ID of the Greenplum Cluster resource to update. To get the Greenplum cluster ID, use a ClusterService.List request.

segmentHostCount : int64

Number of hosts for add to the segment subcluster

addSegmentsPerHostCount : int64

Number of segments per host to add

duration : int64

Redistribute duration, in seconds

parallel : int64

Redistribute process parallelism, 0 - for automatic detection

closeCluster : bool

Deny all client connections during the expand operation

delayRedistribution : bool

Perform redistribution process by small chunks as background activity

Operation

An Operation resource. For more information, see Operation.

id : string

ID of the operation.

description : string

Description of the operation. 0-256 characters long.

createdAt : google.protobuf.Timestamp

Creation timestamp.

createdBy : string

ID of the user or service account who initiated the operation.

modifiedAt : 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.

One of result

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.

• error : google.rpc.Status

  The error result of the operation in case of failure or cancellation.

• 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.
