Now Mop seems like support only Qos0 and Qos1.
Does Mop have the plan to support Qos2 ?
If has, when this feature can be supported ?

Yes, we have the plan to support exactly-once semantic.
But, The specific time still needs to be discussed, once the result is confirmed, it will be updated in this issue.

Best,
Mattison

You can achieve something similar to exactly once by using QoS 1 on a namespace with Pulsar deduplication enabled.
