/**
 * Service Description: Service for doing schema-related operations.
 *
 * <p>This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * <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
 * try (SchemaServiceClient schemaServiceClient = SchemaServiceClient.create()) {
 *   ProjectName parent = ProjectName.of("[PROJECT]");

 *   String schemaId = "schemaId-697673060";
 *   Schema response = schemaServiceClient.createSchema(parent, schema, schemaId);
 * }
 * }</pre>
 *
 * <p>Note: close() needs to be called on the SchemaServiceClient object to clean up resources such
 * as threads. In the example above, try-with-resources is used, which automatically calls close().
