Re: [RESULT] [VOTE] IoTDB Logo
Hi I have updated our website[1] to use logo picture on the navigation bar. It seems that the size of "apache" is too small to see clearly. Do you have any idea about this?

Be lost in April2019 Polding report?
Hi, I find that I cannot find IoTDB on https://wiki.apache.org/incubator/April2019 ... I attached the draft here, IoTDB IoTDB is a data store for managing large amounts of time series data such as timestamped data from IoT sensors in industrial applications. IoTDB has been incubating since 2018-11-18. Three most important issues to address in the move towards graduation: 1. Release the first version; 2. Provide more documents; 3. Attract more contributors; Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? - no. How has the community developed since the last report? - Lenovo Group Ltd donated the Go version of TsFile (IoTDB's file format). - Alibaba Group tried to evaluate IoTDB and sent feedback on the mailing list. - Mailing list: -- dev@mailing list: 123 emails are sent, and can be divided into 43 threads -- reviews@mailing list: more than 480 mails are sent, for code review and new branch creation notifications. How has the project developed since the last report? - 38 PR are merged, 8 PRs are proposed. - 14 authors have pushed 48 commits to master and 193 commits to all branches. - 41 issues (bugs, and feature requests) are logged on JIRA, 22 of them are resolved. - IoTDB Logo is born How would you assess the podling's maturity? - The project is growing. Please feel free to add your own commentary. [ ] Initial setup [ x ] Working towards first release [ x ] Community building [ ] Nearing graduation [ ] Other: Date of last release: - N/A When were the last committers or PPMC members elected? - N/A Have your mentors been helpful and responsive or are things falling through the cracks? In the latter case, please list any open issues that need to be addressed. - very Helpful.

For the first release version
Hi, Now: - The Polding name search has finished [1] - The license self-check is finished [2] And we have some tasks left: - (1) prepare the final code version. - (2) modify the changes file (we have an initial version) - (3) begin to vote... For task (1) and (2): The following PRs have opened for several days, if there is no other feedback, I will merge them: #79 [IOTDB-6]Value filter query optimization #97 [IOTDB-47][IOTDB-54][IOTDB-59][IOTDB-60]Aggregate+GroupBy+Fill #111 try to release memory asap in ReadOnlyMemChunk #123 provide unified query resource control interface Then I will start a long-term test (at least 5 days) with a heavy write workload for checking whether the current version is stable If everything is fine, we can begin task (2) and add a tag on the repository and finish task (1) and (2). And then, begin (3)...

Re: [External] Re: Commit tsfile-go
Yes, I think the main differences will be: 1. The header of a ChunkGroup(called RowGroup previously) is moved to the tail of the data and becomes a footer. 2. As a consequence of 1., there is a marker before each ChunkHeader and ChunkGroupFooter, and there is also a marker before the index at the tail of the file, indicating that the data section is over. 3. The index structure at the tail of a TsFile also changes.

Re: 答复: [External] Re: Commit tsfile-go
Hi, first, I think this is very cool! To avoid this kind of problems (and make further implementations more easy) could we use something like protobuf or Avro or so as Serialization layer for the metadata objects? This would help us to keep all drivers in sync... What do you think?

Hi, After investigation, I found the tsfile format of go version is almost the same with the latest TsFile format of java version, but unfortunately there are some differences between them: They have almost the same meta objects structures, but there are several attributes are not exactly the same.
