public final class BigtableDataSettings

Settings class to configure an instance of BigtableDataClient.

Sane defaults are provided for most settings:

• The default service address (bigtable.googleapis.com) and default port (443) are used.
• The transport provider is configured with a channel pool that contains twice as many connections as CPUs.
• Credentials are acquired automatically through Application Default Credentials.
• Retries are configured for idempotent methods but not for non-idempotent methods.

The only required setting is the instance name.

The builder of this class is recursive, so contained classes are themselves builders. When build() is called, the tree of builders is called to create the complete settings object.

 BigtableDataSettings.Builder settingsBuilder = BigtableDataSettings.newBuilder()
   .setProjectId("my-project")
   .setInstanceId("my-instance-id")
   .setAppProfileId("default");

 BigtableDataSettings settings = builder.build();
 

For fine grained control of individual RPCs, please refer to EnhancedBigtableStubSettings, which is exposed as Builder#stubSettings().

Static Methods

enableBuiltinMetrics() (deprecated)

public static void enableBuiltinMetrics()

Deprecated. This is a no-op that doesn't do anything. Builtin metrics are enabled by default now. Please refer to BigtableDataSettings.Builder#setMetricsProvider(MetricsProvider) on how to enable or disable built-in metrics.

Register built in metrics.

Exceptions
Type	Description
IOException

enableBuiltinMetrics(Credentials credentials) (deprecated)

public static void enableBuiltinMetrics(Credentials credentials)

Deprecated. This is a no-op that doesn't do anything. Builtin metrics are enabled by default now. Please refer BigtableDataSettings.Builder#setMetricsProvider(MetricsProvider) on how to enable or disable built-in metrics.

Register built in metrics with credentials. The credentials need to have metric write access for all the projects you're publishing to.

enableGfeOpenCensusStats()

public static void enableGfeOpenCensusStats()

Beta

OpenCensus stats integration is currently unstable and may change in the future

This feature is covered by the Pre-GA Offerings Terms of the Terms of Service. Pre-GA libraries might have limited support, and changes to pre-GA libraries might not be compatible with other pre-GA versions. For more information, see the launch stage descriptions.

Enables OpenCensus GFE metric aggregations.

This will register views for gfe_latency and gfe_header_missing_count metrics.

gfe_latency measures the latency between Google's network receives an RPC and reads back the first byte of the response. gfe_header_missing_count is a counter of the number of RPC responses received without the server-timing header.

enableOpenCensusStats()

public static void enableOpenCensusStats()

Beta

OpenCensus stats integration is currently unstable and may change in the future

This feature is covered by the Pre-GA Offerings Terms of the Terms of Service. Pre-GA libraries might have limited support, and changes to pre-GA libraries might not be compatible with other pre-GA versions. For more information, see the launch stage descriptions.

Enables OpenCensus metric aggregations.

This will register Bigtable client relevant io.opencensus.stats.Views. When coupled with an exporter, it allows users to monitor client behavior.

Please note that in addition to calling this method, the application must:

• Include openensus-impl dependency on the classpath
• Configure an exporter like opencensus-exporter-stats-stackdriver

Example usage for maven:

{@code
   

   
 

Java: {@code StackdriverStatsExporter.createAndRegister(); BigtableDataSettings.enableOpenCensusStats(); }
