Hi pulsar folks, Currently Pulsar messages has fields for `publish_time`. However in some use cases for example stream computing, `event_time` is required. I'd like to start a proposal to add `event_time` support to pulsar messages.
This proposal only covers adding `event_time` to pulsar messages and make it available to both producers and subscribers. It doesn't cover advanced features, such as event-time index or rewind subscriptions based on event-time. I created the proposal here: https://gist.github.com/sijie/60324cc892643961b923593a597109ab Please go over and provide your feedback/comments. Also, since I don't have any permissions on writing pulsar wiki pages, can any pulsar committers help me add this PIP to the wiki pages if it is accepted? - Sijie
