Google Cloud Datastore Migration Plan
- Write new store paths that use Datastore, controlled by a cmd line flag.
- Write a migration tool that copies data from MySQL to Datastore.
- For each instance of skiaperf:
- Stop app.
- Migrate data.
- Flag flip on instance --use_cloud_datastore.
- Restart app.
- Update DESIGN.md to reflect the new way data is stored.
