Package com.google.cloud.bigtable.admin.v2

Class BigtableInstanceAdminClient

java.lang.Object
com.google.cloud.bigtable.admin.v2.BigtableInstanceAdminClient
All Implemented Interfaces:
AutoCloseable
public final class BigtableInstanceAdminClient extends Object implements AutoCloseable
Client for creating, configuring and deleting Cloud Bigtable instances, app profiles, and clusters.

See the individual methods for example code. 


 // One instance per application.
 BigtableInstanceAdminClient client =  BigtableInstanceAdminClient.create("my-project");
 CreateInstanceRequest request = CreateInstanceRequest.of("my-instance")
   .addCluster("my-cluster", "us-east1-c", 3, StorageType.SSD);

 Instance instance = client.createInstance(request);

 // Cleanup during application shutdown.
 client.close();

Creating a new client is a very expensive operation and should only be done once and shared in an application. However, close() needs to be called on the client object to clean up resources such as threads during application shutdown.

This class can be customized by passing in a custom instance of BigtableInstanceAdminSettings to create(). For example:

To customize credentials: 


 BigtableInstanceAdminSettings settings = BigtableInstanceAdminSettings.newBuilder()
   .setProjectId("my-project")
   .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
   .build();

 BigtableInstanceAdminClient client = BigtableInstanceAdminClient.create(settings);
To customize the endpoint: 

 BigtableInstanceAdminSettings.Builder settingsBuilder = BigtableInstanceAdminSettings.newBuilder()
   .setProjectId("my-project");

 settingsBuilder.stubSettings()
   .setEndpoint(myEndpoint);

 BigtableInstanceAdminClient client = BigtableInstanceAdminClient.create(settingsBuilder.build());
