Sometimes I wonder if I'm the crazy one. Kafka seems to me to be the only sensible foundational datastore out there: it can maintain and propagate a log with all the properties you would want a datastore to have. Relational database seem to be a crazily overengineered solution in search of a problem, with incredibly poor reliability properties (essentially none of them are true master-master HA out of the box, and they tend to require significant compromises to make them so) to boot.
