So probably not, since this is about supporting Postgres on Cloud SQL.
Right. Vitess was built by YouTube to solve its own scalability problems. It provides sharding and cluster-management functionality. In a way, it's orthogonal. We've talked about the possibility of making Vitess work on top of CloudSQL. Maybe it will happen some day.
Sounds like that might take a bite out of the market for Spanner :P
