The natural kappa architecture is to re-bootstrap all state from kafka if necessary from the beginning. Thats were most of the simplicity of this architecture comes from. Implementing such a side kick will just increase complexity by a whole lot because its yet another fight against the architecture. So i hope we can withstand the itchyness of a ticket being there and let the project benefit from leaving this out. Also: Isn't that why kafka supports microservices so well, people could just run flink as a separate consumer was (Author: jfilipiak): Recommendation from my side to leave this feature out.
