> The service.MigrationManager class manages a MIGRATION_STAGE where nodes should execute
db.migration.Migration instances.
> The problem is that the node that a client connects to via Thrift or Avro initiates the
migration in their client thread (calls migration.apply). Instead, the Thrift and Avro clients
should ensure that the migration occurs in MIGRATION_STAGE, and should block until the migration
is applied by the stage.
