Ah, the big data clusters. Those are wicked cool. Also, they're not Availability Group technology. Well, I'm sure some is utilized. However, it's not a traditional AG. Instead, that's a large set of containers managed through Kubernetes. This is utterly different from AG. It's not an availability group, with one database getting all the reads, then transactions replicated across to one or more secondaries, which are readable, and a failover capability. Instead, it's a whole slew of containers, masquerading as a single database, with writes going on all over the place, not one location, but hundreds. It's just a different animal not to be construed with, what is now, old fashioned AG.
