We haven't in depth, as they only advertise with their sharding and distributed query features etc and less with their HA features (if that is even in Citus Community).
Sharding data is something we won't do before we absolutely need it, since disk capacity is not at all our constraint right now and our scaling problem isn't that its hard to serve many tenants at once, but we may need to be able to serve one tenant with very high concurrency the minute their tickets go on sale (which would only affect one shard on a usual sharding setup).
Are you using Citus for HA? Would love to hear your thoughts!
