On: Announcing Vitess 11

[nimrody]

Is Vitess still used by Youtube or did they eventually move to one of Google's internal planet-scale databases?

I heard that YouTube has migrated to Spanner already. YT was the last major user of MySQL at Google, the Googlers probably consider that as a snowflake and wanted to move away from it. Nothing wrong with Vitess itself.

AFAIK it's been done for a while (ex-Googler but non-YT, left recently).

Vitess was most definitely a special snowflake: most Google production servers don't even have disk anymore[0].

(There are a whole host of other reasons for doing Vitess->Spanner, all of which fall under "special snowflake infrastructure".)
