[Service Bus] Limits on ServiceBusMessageBatch

See original GitHub issue

Issue

There is a limit of 4500 messages that can be sent on the link

To repro

put a byte of buffer in the body for each message
keep adding messages with the tryAdd method
A total of 33K messages will be added
Upon sending the batch, service throws an error
If stopped adding messages at 4500, send works perfectly fine

Thanks to @MiYanni for the find!

TODO

Reach out to the service team on the limit
Ideal solution: link should have the max_number_of_messages that can be sent along with the max_size, which could be used to restrict adding messages when tried to add more with tryAdd()
Add a test upon clarifying

Just tested event-hubs, it doesn’t seem to have the same limit. I was able to add the messages until I maxed out w.r.t max_batch_size and could send the batch.

No service doc available about this limit yet. Moving into backlog.
