(experimental) An AppSync datasource backed by RDS.

Example: 

 // Build a data source for AppSync to access the database.
 GraphqlApi api;
 // Create username and password secret for DB Cluster
 DatabaseSecret secret = DatabaseSecret.Builder.create(this, "AuroraSecret")
         .username("clusteradmin")
         .build();
 // The VPC to place the cluster in
 Vpc vpc = new Vpc(this, "AuroraVpc");
 // Create the serverless cluster, provide all values needed to customise the database.
 ServerlessCluster cluster = ServerlessCluster.Builder.create(this, "AuroraCluster")
         .engine(DatabaseClusterEngine.AURORA_MYSQL)
         .vpc(vpc)
         .credentials(Map.of("username", "clusteradmin"))
         .clusterIdentifier("db-endpoint-test")
         .defaultDatabaseName("demos")
         .build();
 RdsDataSource rdsDS = api.addRdsDataSource("rds", cluster, secret, "demos");
 // Set up a resolver for an RDS query.
 rdsDS.createResolver(BaseResolverProps.builder()
         .typeName("Query")
         .fieldName("getDemosRds")
         .requestMappingTemplate(MappingTemplate.fromString("\n  {\n    \"version\": \"2018-05-29\",\n    \"statements\": [\n      \"SELECT * FROM demos\"\n    ]\n  }\n  "))
         .responseMappingTemplate(MappingTemplate.fromString("\n    $utils.toJson($utils.rds.toJsonObject($ctx.result)[0])\n  "))
         .build());
 // Set up a resolver for an RDS mutation.
 rdsDS.createResolver(BaseResolverProps.builder()
         .typeName("Mutation")
         .fieldName("addDemoRds")
         .requestMappingTemplate(MappingTemplate.fromString("\n  {\n    \"version\": \"2018-05-29\",\n    \"statements\": [\n      \"INSERT INTO demos VALUES (:id, :version)\",\n      \"SELECT * WHERE id = :id\"\n    ],\n    \"variableMap\": {\n      \":id\": $util.toJson($util.autoId()),\n      \":version\": $util.toJson($ctx.args.version)\n    }\n  }\n  "))
         .responseMappingTemplate(MappingTemplate.fromString("\n    $utils.toJson($utils.rds.toJsonObject($ctx.result)[1][0])\n  "))
         .build());
