Release Candidate: - IoTDB-0.12.2 RC3 was proposed on 2021-09-08 Besides, we opened a new repo iotdb-web-workbench for IoTDB's new module. ## Community Health: In last quarter report, we reported that the dev@ mailing list traffic decreased. We investigated the reason and find it is because many discussion happens on Confluence document. This quarter, dev@ mailing list is more active (53% traffic increase), for two reasons: (1) we encourage contributors discuss on the dev@, and (2) more new contributors joins. We think the community is back to healthy. Two more things: - The community joined ApacheCon Asia. - The community enabled Github Discussion, which is used for user-help. - The community had a discussion about how to celebrate the first anniversary of IoTDB's graduation from the Incubator. But no a clear consensus up to now. Will keep to discuss.

Besides, we are developing a new feature, called aligned time series, which is very common in many applications. The design document (Chinese)is on IoTDB's confluence. ## Community Health: The good news is we have more and more contributors. It is benefited from GSoC 2021 (though IoTDB has no tasks that are selected finally) and Chinese Summer 2021 of Open Source Promotion Plan. The bad news is the dev@ mailing list traffic decreases, which is a serious signal. The PMC group will keep eye on it and try to improve the public discussion in next quarter.

## Community Health:
According to Github's statistics, the number of IoTDB's code contributors
reaches to 100!
The number of discussions on the dev@ mailing list, the number of PRs
decreases, the Chinese New Year holiday is one of the reasons.
However, we can see the number of emails in the review@ mailing list
increases, it is good because it indicates more discussions happen.
The number of opened issues also increases, which indicates more and
more user requirements are received.

Both the number of participators are 33. But, indeed we saw many new participators in Oct. Besides, we think the number of the email is reasonable as in Sep we have many votes for graduation. - 79 PRs are merged in Sep while 177 PRs are merged in Oct. - Another good thing is some non-developers join the community, for modifying the documents, etc..
## Description:
The Apache IoTDB is an IoT native database with high performance
for data management and analysis on both the edge and the cloud.
## Issues:
There are no new issues requiring board attention at this time.
## Membership Data:
Apache IoTDB was founded 2020-09-16 (a month ago)
There are currently 35 committers and 23 PMC members in this project.
The Committer-to-PMC ratio is roughly 3:2.
Community changes, past quarter:
- No new PMC members (project graduated recently).
- No new committers were added.
- Chao Wang was added as a committer on 2020-09-03 before IoTDB graduated.
## Project Activity:
Software development activity:
- 0.10.1 was released on 2020-08-23.
- We are organizing the design documents on IoTDB's cwiki space
- We are working for v0.11
- Two proposals are submitted and accepted for Outreachy Intern
Meetups and Conferences:
- We had two public talks about IoTDB, one is "Use cases and
optimizations of IoTDB" on ApacheCon 2020, and another is
"IoTDB and Hadoop: Connecting the edge and the cloud open source
ecosystem for IIoT" on Hadoop meetup in Shanghai, China.
## Community Health:
As IoTDB graduated less than 30 days, the statistics provided by
the Board Report Wizard seems incorrect. I count the metrics manually.
As IoTDB has report in Sep, I just count the data in one month:
- Commit activity:
- 434 commits in the last month
- GitHub PR activity:
- 136 PRs opened on GitHub, last month
- 108 PRs closed on GitHub, last month
- JIRA activity:
- 81 issues opened in JIRA, last month
- Mailing list (dev@):
- 196 mails were sent (down 35) and there are 35 participants (down 6)
We think the data fluctuation is reasonable as (1) there are some
participants from China and they have 8 days National Holiday,
(2) there are some Chinese graduate students in the community and they
have summar holiday and are busy at the beginning of a new semester.

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 unfinished issues to address before graduating:
1. Learn to discuss things on the mailing list, rather than just post an
ISSUE created or closed message, or discuss on Github.
2. More committers should know how to release a version. And more PPMC
should join to vote.
3. Write more documentation to help new contributors.
### Are there any issues that the IPMC or ASF Board need to be aware of?
No

- [ ] Other:
1. The community is more diverse than before. As far as the reporter
knows, the contributors come from more than 10 companies/organizers.
2. More users begin to report the bugs, which means that more and more
users are using IoTDB.

close issues.). The permission may need to be fixed.
### Is the PPMC managing the podling's brand / trademarks?
Required Name Search is done. A google search didn’t show any major

### IPMC/Shepherd notes:
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 unfinished issues to address before graduating:
1. Make the community (both the contributors and committers/PPMCs)
more diverse and learn to discuss things on the mailing list.
2. More committers should know how to release a version.
3. Write more documentation to help new contributors.
### Are there any issues that the IPMC or ASF Board need to be aware of?
No.
### How has the community developed since the last report?
1. Some new contributors joined the community. E.g., PR#339 comes
from a new contributor and it is really an interesting feature.
2. Some contributors (who are not committers yet) are more active
than before. E.g., Boris Zhu and Jack Tsai.
3. More users began to report their issues. E.g., issue #171, #184
and #186.
As all the above contributions and contributors are not from the
institutions/companies where initial committers are, we think it is a
good signal that indicates more guys noticing the community.
### How has the project developed since the last report?
1. IoTDB releases its first Apache version: v0.8.0 !
2. IoTDB is more stable and the performance is far better than
before. However, the version is incompatible with previous version (which
are released before IoTDB is denoted to ASF).
3. In v0.8.0, many issues are resolved (see release notes:
http://iotdb.apache.org/#/Materials/Release%20Notes)

Comments: Good to see your first release out, but more active
involvement by the PPMC is needed in veting releases. While it improved,
still more discussion needs to happen on the mailing list.
- [X] (iotdb) Christofer Dutz
Comments: I really would like to see more mailing list usage, cause
the number of commit messages is in strong contrast to the discussions.
I as a mentor some time don't have a clue what the project is working

We can find that IoTDB is becoming a new choice when users need a time
series database. New users from UCI (IoTDB-104), Sangfor Inc., University
of Liverpool (IoTDB-94) etc. are testing and proposing issues for IoTDB.
### How has the project developed since the last report?
1. IoTDB is more stable than before. Now it works well on a VM provided
by Apache (iotdb-vm.apache.org).
