Julian Feinauer commented on IOTDB-528:
---------------------------------------
Yes, indeed I know. I already scratched one for grafana which works reasonably
well... but currently i try to have one that creates the snapshot also : )
{code:java}
FROM openjdk:11-jre-slim
LABEL maintainer="j.feina...@pragmaticminds.de"
RUN mkdir /iotdb
ADD application.properties /iotdb/
ADD iotdb-grafana-0.10.0-SNAPSHOT.war /iotdb/
EXPOSE 8888
WORKDIR /iotdb/
ENTRYPOINT ["java", "-Dspring.datasource.url=jdbc:iotdb://${IOTDB_HOST}:6667",

> [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.
