Vitess V2: Now with more V3
Starting with Vitess v2.0.0-beta.2, the VTGate V3 API can route complex single-shard queries (containing joins, subqueries, aggregation, sorting, and any combination thereof) as well as perform cross-shard joins. That means you no longer need to tell VTGate the keyspace ID that a query targets, as you did with the VTGate V2 API.
The fact that keyspace IDs are now hidden from the application has enabled drop-in Vitess libraries for standard database interfaces like JDBC (written by Flipkart), PDO (written by Pixel Federation), PEP 249, and database/sql.

Vitess 2.0 is now beta!
That means we've accomplished all our planned overhauls of client APIs and backward-incompatible protocol changes. See the release notes for what's new.
We're now working closely with several users who are evaluating Vitess and providing feedback on the use cases that are important for their particular applications and production environments. If you're at the same stage, we welcome you to join the discussion by posting on the mailing list.
