Xiangdong Huang commented on IOTDB-528:
---------------------------------------
OK, if we let users assign how many data points they can bear, I think it makes
sense. Then we can calculate the time interval of the aggregation automatically.
Do you want to use it in the tutorial tomorrow? If not, I can implement
tomorrow. Otherwise, I have to do it tonight..
> [GRAFANA] Implicitly do GROUP BY to avoid sending to many data over the wire

> URL: https://issues.apache.org/jira/browse/IOTDB-528
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Connectors/Grafana
> Reporter: Julian Feinauer
> Priority: Major
> Labels: performance
>
> When using itodb-grafana integration through SimpleJson it seems like it does
> not do any aggregation at all.
> In situations where one selects a big time range it should do some
> subsampling with group by to limit the number of rows being sent.
