When the `IC` is called successfully, it will return a build id, and then `RC` will update the build id to the `collection meta` and record the position of the msgstream in etcd. 4. Step 3 is transactional and the operation will be successful only if the `collection meta` in etcd is updated. 5. So the `RC` only needs to restore the msgstream to the position when recovering from a power failure.
