Julian Feinauer commented on IOTDB-528: --------------------------------------- Exactly, this is what I meant. E.g. we could say we limit to 1000 points. So we always chose the granularity in a way, that we have to transfer fewer than 1000 points. > [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)
