Azure Servicebus queue, BrokeredMessage.SequenceNumbers are not continuous

Question

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

https://learn.microsoft.com/zh-cn/dotnet/api/microsoft.servicebus.messaging.messagereceiver.receivebatchasync?view=azure-dotnet

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

How can I make this continuous?

Did you enable session and also what is the time to live for messages? — Pravallika KV, Dec 23 '22 at 09:36
Session not enabled. The time to live for messages is 14 days. — KKKK, Dec 24 '22 at 07:49

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.
