OrioleDB – solving some PostgreSQL wicked problems
This is exciting:> ...This log architecture is optimized for raft consensus-based replication allowing the implementation of active-active multimaster.I'm a developer but manage 2 PostgreSQL  instances each with an async replica. I also manage 1 three-node CockroachDB cluster. It's night and day when it comes to any type of ops (e.g. upgrading a version). There's a lot of reasons to use PostgreSQL (e.g. stored procedures, extensions, ...), but if none of those apply to you, CockroachDB is a better default.I just finished interviewing someone who went into detail about the difficulty they're having doing a large scale migration or a mission critical large PG cluster (from one DC to another)..it's a multi-team, year long initiative that no one is comfortable about.In my experience, PG is always the most out-of-date piece of any system. I still see 9.6 here and there, which is now EOL.
