Cursor Issue

I have been trying out this driver and it has been working well with vertx and I can retrieve all results well. I do have memory issues so I tried the streaming option which only loaded the first results and no others. So I have moved one step back to the cursors and I am getting the same problem. With the following I only receive the first values. The while loop runs once where it should run multiple times and even on the first iteration within there are no results.

PgPool pool = PgClient.pool(vertx.getDelegate(), options);

        pool.getConnection(ar1 -> {
            if (ar1.succeeded()) {
                PgConnection connection = ar1.result();
                Buffer sql = vertx.fileSystem().readFileBlocking("sql/test.sql");
                connection.prepare(sql.toString(), ar2 -> {
                    if (ar2.succeeded()) {
                        resultHandler.handle(Future.succeededFuture(new JsonObject().put("started", true)));
                        PgPreparedQuery pq = ar2.result();
                        PgCursor cursor = pq.cursor(Tuple.of("test"));

                        cursor.read(5, ar3 -> {
                            PgRowSet rows = ar3.result();
                            JsonArray jsonResults = new JsonArray();
                            PgIterator iterator = rows.iterator();
                            while (iterator.hasNext()) {
                                Row result = iterator.next();
                                jsonResults.add(result);
                            }
                            logger.info(jsonResults);

                            while (cursor.hasMore()) {
                                cursor.read(5, ar4 -> {
                                    PgRowSet rows2 = ar4.result();
                                    JsonArray jsonResults2 = new JsonArray();

                                    PgIterator iterator2 = rows2.iterator();
                                    while (iterator2.hasNext()) {
                                        Row result2 = iterator2.next();
                                        jsonResults2.add(result2);
                                    }
                                    logger.info(jsonResults2);
                                });
                            }
                        });
                    }
                    else {
                        resultHandler.handle(ServiceException.fail(CONNECTION_FAILED, ar2.cause().getMessage()));
                    }
                });

@yonigibbs I believe it’s quite solid and production read, if there are issues we fix them as soon as we can and issue fixes (there are people already using it in production).

thanks a lot
