existing leveldbstore here? Seems like some operations need to acquire locks?
> More generalized timeline ACLs

> We need to differentiate the access controls of reading and writing
> operations, and we need to think about cross-entity access control. For
> example, if we are executing a workflow of MR jobs, which writing the
> timeline data of this workflow, we don't want other user to pollute the
> timeline data of the workflow by putting something under it.
