// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Settings class to configure an instance of {@link DataprocMetastoreStub}.
 *
 * <p>The default instance has everything set to sensible defaults:
 *
 * <ul>
 *   <li>The default service address (metastore.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 total timeout of getService to 30 seconds:
 *
 * <pre>{@code
 * DataprocMetastoreStubSettings.Builder dataprocMetastoreSettingsBuilder =
 *     DataprocMetastoreStubSettings.newBuilder();
 * dataprocMetastoreSettingsBuilder
 *     .getServiceSettings()
 *     .setRetrySettings(
 *         dataprocMetastoreSettingsBuilder
 *             .getServiceSettings()
 *             .getRetrySettings()
 *             .toBuilder()
 *             .setTotalTimeout(Duration.ofSeconds(30))
 *             .build());
 * DataprocMetastoreStubSettings dataprocMetastoreSettings =
 *     dataprocMetastoreSettingsBuilder.build();
 * }</pre>
