Supporting Similarity Search in IoTDB: Scenarios, SQL and Result Format

Hi all: I hope to let IoTDB support similar research by adding the indexing mechanism. Similarity search is one of the most important directions in the field of time series, and some users have shown their requirements for similarity search. Different from the existing query conditions in

Re: Embdedded IoTDB Grafana Endpoint

Hi, I dislike the idea of having spring in the server as well. +1, could we combine the small handler with our RestAPI? 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: "Julian Feinauer" 发送时间: 2020-11-06 22:38:50 (星期五) 收件人:

IoTDB Travis CI is back to normal

Hi, recently our Travis CI is not stable because there are some tests failure because of "ports not closed" or "mergeTasks not finished".. After some fixes [1], [2] and [3], now I believe the Travis CI is back to normal, WHICH MEANS if you see CI failure on your PR, please double-check why...

Re: Embdedded IoTDB Grafana Endpoint

Hey, yes, to do it clean we could do it directly without Spring. Then ist just a very small handler. Similar to what we already use optionally in the prometheus module. I dislike the idea of having spring in the server as well. Julian Am 06.11.20, 12:03 schrieb "Xiangdong Huang" : Hi,

Nice! I want this feature for about one year!! Will review the design document tonight. Best, --- Xiangdong Huang School of Software, Tsinghua University 黄向东 清华大学 软件学院 Houliang Qi 于2020年11月6日周五 下午5:51写道： > Nice work! > This will enrich the ecology of IoTDB.

Re: Embdedded IoTDB Grafana Endpoint

Hi, > what do you think of an option to run the SimpleJson Grafana Connector directly in IoTDBs Server Context (could be disbaled by default). it is ok. But I think we need to prune some dependencies of Spring... It it too large now.. (I remember it is ~ 20MB to add such a module) Best,

Embdedded IoTDB Grafana Endpoint

Hi folks, as we just discussed the prometheus integration, what do you think of an option to run the SimpleJson Grafana Connector directly in IoTDBs Server Context (could be disbaled by default). This would make it way easier for users to just „look“ aat their IoTDB Data. WDYT? Julian

SDT Encoding and Query Design

Hi, The following is a more detailed design[1] of SDT encoding and query in IoTDB. The encoding and query methods will consult OSISoft Pi's design. The document first explains Pi's approach to encoding and query, then shows the modification of PageWriter, PageReader, SDTEncoder, SDTDecoder.

Iotdb integrated Prometheus

Hi,all The following is the design of iotdb integrated Prometheus. https://cwiki.apache.org/confluence/display/IOTDB/Iotdb+integrated+Prometheus As mentioned inhttps://issues.apache.org/jira/projects/IOTDB/issues/IOTDB-519?filter=allopenissues, IoTDB is a highly efficient time series
