We're planning to support Kafka as described in Thoughts on Eventuate's future
). There will for sure be a replication bridge between Eventuate 1.0 and Calliope event logs, maybe even a Kafka storage plugin for Eventuate 1.0 based on Calliope components, depending on user requests. I'm about to collect further requirements for Calliope at the moment and also currently writing a prototype which will be published soon. WDYT?
