> After we finished the design for time-based aggregation, we can adopt our
> existing Phoenix storage into the storage of the aggregated data. In this
> JIRA, I'm proposing to refactor writers to add support to aggregation
> writers. Offline aggregation writers typically has less contextual
> information. We can distinguish these writers by special naming. We can also
> use CollectorContexts to model all contextual information and use it in our
> writer interfaces.
