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

- ericyan 5y agoI 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.
- joatmon-snoo 5y agoAFAIK 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".)
