Examples with BigtableClusterName com.google.cloud.bigtable.grpc.BigtableClusterName used on opensource projects

Example 1 with BigtableClusterName

use of com.google.cloud.bigtable.grpc.BigtableClusterName in project java-docs-samples by GoogleCloudPlatform.

the class BulkWrite method getClusterNodeCount.

// Get the number of nodes for the Bigtable instance. This only works for single cluster instances
// so it will treat multi-cluster instances as single node clusters.
private static int getClusterNodeCount(String projectId, String instanceId) throws IOException, GeneralSecurityException {
    try {
        BigtableClusterUtilities clusterUtility = BigtableClusterUtilities.forInstance(projectId, instanceId);
        Cluster cluster = clusterUtility.getSingleCluster();
        String clusterId = new BigtableClusterName(cluster.getName()).getClusterId();
        String zoneId = BigtableClusterUtilities.getZoneId(cluster);
        int clusterNodeCount = clusterUtility.getClusterNodeCount(clusterId, zoneId);
        System.out.println("Cluster size " + clusterNodeCount);
        return clusterNodeCount;
    } catch (IllegalStateException e) {
        System.out.println("Unable to get cluster size. Treating as single-node cluster.");
        return 1;
    }
}

Example 2 with BigtableClusterName

use of com.google.cloud.bigtable.grpc.BigtableClusterName in project java-bigtable-hbase by googleapis.

the class BigtableAsyncAdmin method getBackupClusterName.

    if (this.bigtableSnapshotClusterName == null) {
        List<Cluster> clusters = asyncConnection.getBigtableApi().getAdminClient().listClusters(asyncConnection.getBigtableSettings().getInstanceId());
        Preconditions.checkState(clusters.size() == 1, String.format("Project '%s' / Instance '%s' has %d clusters. There must be exactly 1 for this operation to work.", asyncConnection.getBigtableSettings().getProjectId(), asyncConnection.getBigtableSettings().getInstanceId(), clusters.size()));
        String clusterName = NameUtil.formatClusterName(asyncConnection.getBigtableSettings().getProjectId(), asyncConnection.getBigtableSettings().getInstanceId(), clusters.get(0).getId());
        bigtableSnapshotClusterName = new BigtableClusterName(clusterName);
