+/**
+ * Settings class to configure an instance of {@link BaseBigtableInstanceAdminClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (bigtableadmin.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>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.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getInstance:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * BaseBigtableInstanceAdminSettings.Builder baseBigtableInstanceAdminSettingsBuilder =
+ *     BaseBigtableInstanceAdminSettings.newBuilder();
+ * baseBigtableInstanceAdminSettingsBuilder
+ *     .getInstanceSettings()
+ *     .setRetrySettings(
+ *         baseBigtableInstanceAdminSettingsBuilder
+ *             .getInstanceSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());

+ *     baseBigtableInstanceAdminSettingsBuilder.build();
+ * }</pre>
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * <p>To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for createInstance:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * BaseBigtableInstanceAdminSettings.Builder baseBigtableInstanceAdminSettingsBuilder =
+ *     BaseBigtableInstanceAdminSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * baseBigtableInstanceAdminSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }</pre>
