Julian Feinauer commented on IOTDB-528: --------------------------------------- Hey [~hxd] , my simple idea was to have a fixed rule which performs a group by query depending on the time range (you get from SimpleJSON). We could also make this optional in the config. > [GRAFANA] Implicitly do GROUP BY to avoid sending to many data over the wire > ---------------------------------------------------------------------------- > > Key: IOTDB-528 > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
