> Is it possible to add a per-ordering-key sequence number (or monotonic timestamp) as a message attribute, then reorder in the pipeline per-key? hi @liferoad, I've tried this approach, it brings additional latency (~0.5s) and there are still edge elements which could be in a wrong order - for example, last element of first "window" and first element of second one. So from my point of view key should be assigned in an output of pubsubio to prevent it, but I would love to hear Expert opinions about downsides of this. Our case is latency and ordering sensitive, KafkaIo just doing fine there, and I'm a bit surprised noone requested the feature for PubSub before. -- This is an automated message from the Apache Git Service.
