> 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.
