Thank you all again. I take this opportunity to share with you what we are doing here at ArcelorMittal AMERICAS.
We are using to paths for sensor data : 1) OPC UA Server -> miNiFi -> NiFi -> HBase/HDFS Parquet -> Spark for further analysis. 2) OPC UA Server -> miNiFi -> NiFi -> Microsoft Power BI for real-time dashboards and reports. Some data sensors also can be submited using MQTT -> NiFi ….. What we are trying to do. Replace the HBase/HDFS for IOTDB and add Grafana as an alternative to Power BI. I’ve seen you talking about miNiFi/NiFi support and improve Grafana connection, these are a very important integrations to us. Until the NiFi integration becomes available, I will follow your recommendation : OPC UA Server -> miNiFi -> NiFi -> SPARK -> TSFILE -> Script > IOTDB > Grafana As soon as you release the version 0.10 I will upgrade to take the benefits that you mention. Once again, thank you all. > On 26 Mar 2020, at 00:23, Xiangdong Huang <saint...@gmail.com> wrote: > > Hi, > > As it is a version range, claim the info clearly in user guide document is > needed, I think. > > ----------------------------------- > Xiangdong Huang > School of Software, Tsinghua University > > 黄向东 > 清华大学 软件学院 > > > 孙泽嵩 <sz...@mails.tsinghua.edu.cn> 于2020年3月26日周四 上午11:16写道: > >>> @zesong, can we put the minimal version requirement of Spark on our doc >> or readme? >> Maybe I can modify the version to “> 2.2.0”?
