One more feature:
max-length
limit for publications without confirms when overflow behaviour is reject-publish
.Priorities (at least two) from my POV are mandatory. We can't migrate our classic queues to quorum without priorities
Please can you elaborate on your use case? Especially why you need priority queues rather than use by multiple queues. Also what kind of prefetch do your priority consumers use?

Yes, you usually can. By using multiple queues instead of just one with priorities.
This belongs to a discussion.
This is a prioritised list of required and optional features for the next version of quorum queues. Due to quorum queues' Raft internals it makes sense for us to bundle a set of features into a single change and this issue aims to capture and discuss the features for the next iteration.
Required:
enqueue
,settle
andcredit
Optional:
Implementation details
Fair/share priorities
Consumer timeouts
Single Active Consumer Priorities
The waiting consumers list should be sorted by consumer priority. When a consumer with a higher priority than the current active one attaches it would demote the current active one. This could provide a means for users to achieve better consumer app balances and avoid the all consumer on one app issue when using multiple queues with SAC.
Checkpoints
Consumer cancel option that immediately removes consumer and returns all pending messages.
