> If the agent fails over after having checkpointed a new operation but before the operation status update stream is created, the recovery process will fail.
> This happens because agent will try to recover the operation status update streams even if it hasn't been created yet.
> In order to prevent recovery failures, the agent should obtain the ids of the streams to recover by walking the directory in which operation status updates streams are stored.
> The agent should also garbage collect streams if the checkpointed state doesn't contain a corresponding operation.
