> we need to change the data model to restrict the data type of
> info/config/metric section.
> 1. Info: the value could be all kinds object that is able to be
> serialized/deserialized by jackson.
> 2. Config: the value will always be assumed as String.
> 3. Metric: single data or time series value have to be number for aggregation.
> Other than that, info/start time/finish time of metric seem not to be
> necessary for storage. They should be removed.
