Our goal is to enable realtime analytics on Postgres without requiring an external analytics database. Think more towards extending Postgres, rather than replacing it. Postgres brings it's rowstore to Hydra, which is great for transactional jobs. Also, Postgres brings it's syntax, features, and standard Postgres integrations with tools you like to use are the same and works with Hydra. This makes Hydra easy to use and adopt without a major database migration.
