Very cool. This is Sai, ex-Citus and currently PeerDB. You are promising many features incl. region aware tenant placement, tenant level metrics, easy tenant isolation etc. which would really help multi-tenant SaaS customers. Back during my days at Citus, we spent many cycles to a build a database for SaaS. We built some (not all) the features you mentioned and saw customers really finding value.
Congrats on the launch. I would love to try out Nile in the future!
