Class BigtableDataSettings (2.10.1)

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

enableGfeOpenCensusStats()

public static void enableGfeOpenCensusStats()

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()

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(); }

newBuilder()

public static BigtableDataSettings.Builder newBuilder()

Create a new builder.

If emulator configuration provided in BIGTABLE_EMULATOR_HOST environment variable then it creates a builder preconfigured to connect to Bigtable using emulator hostname and port number.
