shards can deny access to other functions”. These two issues allowed a malicious user to create a resource that would then subsequently disallow other operations for other users. For example, a user could prevent other users from fetching or creating shards. The issues would disallow actions against other resource types as well, thus resulting in a denial of service attack vector. The issues were more significant authorized. In VTAdmin, authorization checks whether an actor can perform an action against a given resource. The logic is implemented here: https://github.com/vitessio/vitess/tree/main/go/vt/vtadmin/rbac

In the new scheme, since we explicitly control the commit order, there’s no need to follow this implicit order. Instead, we can commit the shard

These tablet type specific redirects will be used to control how we transition the cutover from commerce to customer. A successful completion of this job should "SetShardTabletControl -blacklisted_tables=customer ,corder -remove commerce/0 master" These ‘control’ records were added by the MigrateServedFrom command during the cutover to prevent the commerce tables
