I remember doing 900k writes/s (non-replicated) already back on kafka 0.8 with a random physical server with an old fusionio drive (says something about how long ago this was :D).

It's a fair point that if you already have a pgsql setup, and only need a few messages here and there, then pg is fine. But yeah, the 96 vcpu setup is absurd.
