Azure Servicebus queue, BrokeredMessage.SequenceNumbers are not continuous

I'm using this MessageReceiver.ReceiveBatchAsync Method to receive a batch of messages from a service bus queue.

BrokeredMessage has a SequenceNumber, but sometimes the numbers are not continuous. Does that mean some messages lost.

How can I make this continuous?

Solution

  • BrokeredMessage has a SequenceNumber, but sometimes the numbers are not continuous. Does that mean some messages lost

    The message sequence is set on the broker whenever the broker receives messages. So if you have scheduled messages and it's not the time yet, you'll have a gap between message sequence numbers. Messages are not lost once received by the broker. You shouldn't use sequence numbers as indicators.
