/**
 * Catalog for
 * <a href="https://docs.confluent.io/current/schema-registry/schema_registry_tutorial.html">Confluent Schema Registry</a>.
 * It allows to access all the topics of current Confluent Schema Registry Service
 * through SQL or TableAPI, there is no need to create any table explicitly.
 *
 * <p>The code snippet below illustrates how to use this catalog:
 * <pre>
 *     ConfluentSchemaRegistryCatalog catalog = new ConfluentSchemaRegistryCatalog(
 * 			properties,
 * 			schemaRegistryURL,
 * 			"catalog1",
 * 			"db1");
 * 		tEnv.registerCatalog("catalog1", catalog);
 *
 * 		// ---------- Consume stream from Kafka -------------------
 *
 * 		String query = "SELECT\n" +
 * 			"  id, amount\n" +
 * 			"FROM catalog1.db1.transactions1";
 * </pre>
 *
 * <p>We only support TopicNameStrategy for subject naming strategy,
 * for which all the records in one topic has the same schema, see
 * <a href="https://docs.confluent.io/current/schema-registry/serializer-formatter.html#how-the-naming-strategies-work">How the Naming Strategies Work</a>
 * for details.
 *
 * <p>You can specify some common options for these topics. All the tables from this catalog
 * would take the same options. If this is not your request, use dynamic table options set up
 * within per-table scope.
