Hi, I have read the document, a clear design!
Just one point I'd like to discuss: > For each query, we generate multiple queries: > select country from root.sg0.*.B > select country from root.sg0.*.B.* > select country from root.sg0.*.B.*.* By this means, you need to combine three results in the connector. How about adding a new grammar, such as: select country from root.sg0.*.B.** B.** could match B, B.*, B.*.*, B.*.*... This is an optimization and an extension of IoTDB, not a blocking issue :) Thanks, -- Jialin Qiao School of Software, Tsinghua University 乔嘉林 清华大学 软件学院 > -----原始邮件----- > 发件人: "Xiangdong Huang" <[email protected]> > 发送时间: 2020-11-06 19:05:03 (星期五) > 收件人: dev <[email protected]> > 抄送: > 主题: Re: Iotdb integrated Prometheus > > Nice!
