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	AddClusterHostsMetadata 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	Cluster 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.

Field	Description
max_connections	google.protobuf.Int64Value Maximum number of inbound connections on master segment
max_slot_wal_keep_size	google.protobuf.Int64Value Specify the maximum size of WAL files that replication slots are allowed to retain in the pg_wal directory at checkpoint time. https://www.postgresql.org/docs/current/runtime-config-replication.html
gp_workfile_limit_per_segment	google.protobuf.Int64Value Sets the maximum total disk size that all running queries are allowed to use for creating temporary spill files at each segment. The default value is 0, which means a limit is not enforced. https://docs.vmware.com/en/VMware-Greenplum/6/greenplum-database/ref_guide-config_params-guc-list.html#gp_workfile_limit_per_segment
gp_workfile_limit_per_query	google.protobuf.Int64Value Sets the maximum disk size an individual query is allowed to use for creating temporary spill files at each segment. The default value is 0, which means a limit is not enforced. https://docs.vmware.com/en/VMware-Greenplum/6/greenplum-database/ref_guide-config_params-guc-list.html#gp_workfile_limit_per_query
gp_workfile_limit_files_per_query	google.protobuf.Int64Value Sets the maximum number of temporary spill files (also known as workfiles) allowed per query per segment. Spill files are created when executing a query that requires more memory than it is allocated. The current query is terminated when the limit is exceeded.
