```
   Future<Void> writeAndFlushPromise =
                cnx.getCommandSender().sendMessagesToConsumer(consumerId, topicName, subscription, partitionIdx,
                        entries, batchSizes, batchIndexesAcks, redeliveryTracker, epoch);
        writeAndFlushPromise.addListener(status -> {
            // only increment counters after the messages have been successfully written to the TCP/IP connection
            if (status.isSuccess()) {
                msgOut.recordMultipleEvents(totalMessages, totalBytes);
                msgOutCounter.add(totalMessages);
                bytesOutCounter.add(totalBytes);
                chunkedMessageRate.recordMultipleEvents(totalChunkedMessages, 0);
            }
        });
```

maybe this write fail
