Great stuff. A couple of questions:
- Doesn’t projecting through Kafka look like overkill over catch-up subscriptions, skipping the fact that subscriptions tend to fail on overflow? I think this issue can be fixed, then there will be no need for Kafka there?
- Greg was telling that they want to work (or already working) on weaker consistency replication model, specifically targeting cross-datacentre replication scenario. Have you talked to them before jumping to build your own store?
- Do you have plans to open-source your replication component? It would be really cool to look at what you guys have done.
