The dead letter queue feature is landed and the +notification retry policy feature is almost there. For Queens release, things +I'd like to do which we haven't completed in Pike are: + +1. Scalability + In Zaqar, we would like to see no obvious degradation of latency or +availability when load increasing. Here "load" can refer to various dimensions +of usage: + 1) number of publishers + 2) number of subscribers + 3) rate of messages published or consumed + 4) number of messages + 5) number of queues + 6) size of messages +Above are the "load" we care about in order from my view. We got some +interesting data with OSProfiler and improved/fixed some issues in Pike. But +still need to continue this work to get better performance. + +2. Availability + Zaqar has a simple architecture which makes keeping its availability +relatively easy, for the service level. But we do still need more consideration +for the storage backend layer. + +3. Latency + Latency is a typical, important time-based measure for a messaging service. +Obvious, Zaqar would like to minimize latency wherever possible. There are three +most important latency metrics I would like to improve are: + 1) The amount of time to deliver message from producer zaqar server + 2) The amount of time to deliver message from zaqar to consumer(poll or push) + 3) The amount of time to claim a message + +It's a fantastic experience working with this amazing team and I would be +pleased to serve as PTL for another cycle and I'd appreciate your vote. + +Thanks for your consideration!
