        ListSchemaMappingsRequest mappingsRequest = ListSchemaMappingsRequest.builder()
            .build();

        ListSchemaMappingsPublisher paginator = getResolutionAsyncClient().listSchemaMappingsPaginator(mappingsRequest);

        // Iterate through the pages of results
        CompletableFuture<Void> future = paginator.subscribe(response -> {
            response.schemaList().forEach(schemaMapping ->
                logger.info("Schema Mapping Name: " + schemaMapping.schemaName())
            );

        // Wait for the asynchronous operation to complete
        future.join();
    }
