Xiangdong Huang commented on IOTDB-528: --------------------------------------- Hi julian, you mean that suppose we have a parameter called granularity, and granularity=5s, then we return the downsampling result no matter whether users want to read the raw data? > [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)
