Managed Service for MySQL API, gRPC: ClusterService.ListHosts

Field

Description

clusterId

string

Required field. ID of the cluster to list hosts for.

To get this ID, make a ClusterService.List request.

pageSize

int64

The maximum number of results per page to return.

If the number of available results is larger than pageSize, the API returns a ListClusterHostsResponse.nextPageToken that can be used to get the next page of results in the subsequent ClusterService.ListHosts requests.

pageToken

string

Page token that can be used to iterate through multiple pages of results.

To get the next page of results, set pageToken to the ListClusterHostsResponse.nextPageToken returned by the previous ClusterService.ListHosts request.

Field

Description

hosts[]

Host

List of hosts in the cluster.

nextPageToken

string

The token that can be used to get the next page of results.

If the number of results is larger than ListClusterHostsRequest.pageSize, use the nextPageToken as the value for the ListClusterHostsRequest.pageToken in the subsequent ClusterService.ListHosts request to iterate through multiple pages of results.

Each of the subsequent ClusterService.ListHosts requests should use the nextPageToken value returned by the previous request to continue paging through the results.
