Vitess Online Schema Migration Automation
summary
Vitess claims to let you issue one ALTER TABLE and automate per-shard online DDL by writing a request into topology and having vttablet schedule gh-ost or pt-osc across each shard, returning a job UUID to track status; it creates temporary accounts, bundles gh-ost binaries, throttles by replica roster, records results in a schema_migrations table, cleans up triggers and shadow tables, and the demo shows it completing across four shards.
