# Incubator PMC report for September 2019

The Apache Incubator is the entry path into the ASF for projects and 
codebases wishing to become part of the Foundation's efforts.

This monthly report is in markdown so that it's easier to read. If you are 
not viewing this in that format, it can be seen here:
https://cwiki.apache.org/confluence/display/INCUBATOR/September2019

There are presently 48 podlings incubating. In August, podlings executed 
TODO9 distinct releases. We added three new IPMC members and no IPMC members 
retired.

We have onetwo new podlingpodlings this month DolphinScheduler and MesaTEE. There have 
been a 
couple of ongoing enquires about new projects, and some proposals are 
being 
worked on. A couple of podlings are heading towards graduation in the 
next 
few months. Druid was up for graduation last month but withdrew as 
there's 
a trademark issue with its name.

Several podlings Amaterasu, Superset, Tamaya and Tephra didn't
 submit a report and 
have been asked to do so next month. Tamaya has now
 failed to report twice 
in a row.

Amaterasu has failed to report three times in a row. It looks like the 
PPMC is missing and there's little or no activity on the list. One final 
chance will be given to the project to explain what it status it and how it 
hopes to graduate before it is asked to retire.

Omid and ShardingSphere submitted insufficient reports and will be
asked to report next month.

A few mentors have been added and removed in various projects.

There were 3 IP clearances.

The incubator web site menu was reorganized to group similar content 
together, and further work was done on simplifying the language used on the 
incubator policy page. A few other pages were also improved.

The new disclaimer policy accepted by the board last month has received 
good feedback, and we've had a podling already make a release with it. The 
board asked for some updated documentation on the new disclaimer, and that 
was undertaken.

Some podlings are still struggling to get 3 +1 votes on their release by 
mentors and other IPMC votes are needed to make releases. However, those 
votes seem to be happing quite quickly with several IPMC members checking 
releases.
 
A new mentor guidance document is n the process of being created, so far 
not many mentors have contributed to this. Given the many years of 
experience over many mentors, it would be nice to see mentors contribute to 
this.  This document would help future mentors and podling deal with 
everyday situations that come up that they may be unsure of how to deal 
with.

The IPMC consider dropping that ASF member can join just back asking. 
Looking at mentor it more than that mentors join this way go missing, other 
than those who are voted it. Some IPMC member didn't think this was a good 
idea, so the policy stands.

There was a long discussion on the requirement of IPMC vote on podling 
release which included several suggested changes to policy and new ideas. 
Consensus was not able to be reached on any changes, and the discussion has 
stalled. The main issue being that PMC votes are needed on releases and 
some IPMC members want to do away with IPMC votes on releases altogether.
A new  project was suggested as an experiment to try this out (exact details
still to be worked out), but so far that has not happened. It was even
suggested by a couple of IPMC members that a new incubator project be made.

It may be best to wait until we see the impact of the work in progress
disclaimer before revisiting the IPMC vote situation.

There will be a Podling's Shark Tank at the upcoming ApacheCON North 
America and server talks on incubating subjects and projects.

ECharts is showing slow progress and thought they were ready to graduate
when they were not. A face to face meeting with several experienced IPMC
members has been organized at ApacheCon to get them back on the right track.

There was a discussion on the private on some podlings that probably
should be retired.

  2. Extend the amount of committers. The plan here is to participate in
  a number of conferences, starting with ApacheConf in Berlin on October 23,
  EPAM SEC conference in Gansk on SolutionsHub area
  3. After release 2.2 is made, the team will have to do major refactoring
  of the code, updating of product documentation, which might potentially
  slow down the process of releasing version 2.3

### Are there any issues that the IPMC or ASF Board need to be aware of?

  No issues.

### How has the community developed since the last report?

  A new committer is added:

  files are signed off and submitted, waiting for Apache ID to be created.

### How has the project developed since the last report?

  Team is actively working on release 2.2 features.
  There will be many new features and conceptual changes introduced in
  upcoming release. We are introducing the concept of projects within DLab,
  which will allow to control permissions for groups of DLab users,
  improve collaboration capabilities.
  Major improvements will be made in terms of GCP platform deployment.
  GCP will support the majority of the features, currently available in
  DLab for AWS and Azure Clouds.
  One of the conceptual features implemented is the ability to provision
  DLab's self-service noe in k8s and being able to integrate with many
  identity providers, supporting OAuth2 and SAML2.0 via Keycloak.

  2. One or more Apache Releases as an Incubator project
  3. Documentation improvements

### Are there any issues that the IPMC or ASF Board need to be aware of?

  None

### How has the community developed since the last report?

  * Takuya (PPMC) will give a talk at ApacheCon, LAS VEGAS.
  * Got and merged a pull request from new external contributor.
  * Github watchers/stars are gradually increasing:
    234 stars as of Mar 1 (was 199 on Mar 1)
  * Twitter account @ApacheHivemall followers are gradually increasing:
    208 followers as of Mar 1 (was 189 on Mar 1)

### How has the project developed since the last report?
  
  * Working toward the 3rd Apache release. After HIVEMALL-245 is fixed,
    it will be ready to the vote.

  Since the last report, we have
   * In the last 3 months, we opened 10 JIRA issues and closed 7 JIRA
   issues as seen in https://goo.gl/QFQEF5 (as of Sept 5)
   * Created 7 Pull Requests and closed 5 Pull Requests between May 1st and 
   Aug 31th

### How would you assess the podling's maturity?

The page of community growth is slow. No much active developers.

Considering a pivot of the project scope to get more attention:  
moving from Hive/Spark to a standalone library focusing on Python/Jupyter 
notebook integration.

--------------------
## IoTDB

  IoTDB is a data store for managing large amounts of time series data such as
  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 
  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
   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.

Myriad enables co-existence of Apache Hadoop YARN and Apache Mesos together
on the same cluster and allows dynamic resource allocations across both
Hadoop and other applications running on the same physical data center
infrastructure.

Myriad has been incubating since 2015-03-01.

### Three most important unfinished issues to address before graduating:

  1. Builds Apache Myriad releases regularly
  2. Attract more users and contributors. Community growing.
  3. Attract new mentors for helping the project towards the Apache Way.

### Are there any issues that the IPMC or ASF Board need to be aware of?

  We need new mentors, we have only one active mentor right now.
  We have to increase the community and we have to increase the number
  of mentors too in order to help us to address the Apache way with solid 
  foundations.

### How has the community developed since the last report?

  We have four active committers (PPMCs) right now. A new committer since the
 
 the last report.
  This is a small increment from the community growing point of view, but 
  it 
  helps regarding the
  minimal amount of PPMCs for achieving a release cycle
  with regularity.

### How has the project developed since the last report?

  The most important thing is the activity of creating new releases in a
  regular way. The Apache resources (project page, documentation page, …)
  are maintained and enhanced with new content. Taking into account the 
  effort of rebooting the
  project (more than two years orphaned), the project is slowly addressing 
  the right way, and
  we consider the project is successfully rebooted right now. This state 
  allow us working towards
  attract new users and contributors in our humble opinion.

### Date of last release:

  The 0.4.0 release was issued on Aug 25, 2019

### When were the last committers or PPMC members elected?

  2019-08-02 New committer/PMC member Oscar Fernandez

### Have your mentors been helpful and responsive?
  We have only two mentors right now. One of the is for ever missing, 
  and the other is ready for help when the project needs. So we have only 
  one active mentor. This is an issue to address with the help of IPMC.

   with engineers working with Apache Beam. There had been people 
   from various companies, as Shopify and Seznam.cz, facing problems 
   as large-shuffle and data skew, and had shown a lot of interest 
   in using the Apache Nemo runner. Also, in the following ApacheCon 
   summit happening in Vegas in September, the Apache Beam team will 
   demonstrate running their workloads using the Apache Nemo runner.

  Not much to report, progress is slow-paced as usual. This isn't to say that
  that the project is dormant or in danger of retirement, just that the pace
  is
  to be considered more casual. There is oversight, and important issues are
  being addressed in a timely manner.

### How has the project developed since the last report?
  No noteworthy change, we are operating at a pretty stable level.

## SDAP

SDAP is an integrated data analytic framework for Big Science problems.

SDAP has been incubating since 2017-10-22.

### Three most important issues to address in the move towards graduation:

  1. Make official SDAP (Incubating) Release
  2. Improve/create user guide documentation
  3. Improve committer participation

### 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?

  We are continuing to attract new committers.

### How has the project developed since the last report?

  SDAP is still working towards its first release. Work towards a repeatable
 
 repeatable build pipeline has been started.

  New functionality has been added to the Distributed Oceanographic Matchup 
  Service (DOMS) and Extensible Data Gateway Environment (EDGE) components 
  that allow for filtering in situ measurements by a standardized quality 
  flag.

### How would you assess the podling's maturity?

  There are several deployments of SDAP actively being used and interest is 
  high. However, active participation from project members is low. A push is 
  is needed to cross the t's and dot the i's in regards to meeting the 
  requirements Apache has for releasing software so that we can claim a 1.0 
  version of SDAP.

  A quick look at that stats, without explanation, suggests to me that this
  project is in trouble,. You have a large number of contributors, and
  outstanding pull request, but are not voting committers in.
  Please discuss with your mentors what the committer bar should be and
  what it means to be a committer.

## Spot

Apache Spot is a platform for network telemetry built on an open data model
and Apache Hadoop.

Spot has been incubating since 2016-09-23.

### Three most important unfinished issues to address before graduating:

  1. Revive community activity (Discussion in mailing lists, increase 
  frequency of commits)
  2. Create a new roadmap and release plan that will improve adoption.
  3. Make it easier to contribute to the project (e.g. documentation, 
  framework).

### 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?

  Unfortunately there has not been much more community activity. However, we 
  we are need of more committers as there are only a couple of active committers
 
 committers at this time. This creates a bottleneck which makes it hard
  for the 
  community to grow in interest.

### How has the project developed since the last report?

  There are a series of PRs that have been evaluated for the SPOT-181 epic, 
  and Spot website branch (asf-site) that are in the process of being 
  merged. We 
  have enough votes to merge, and have put out a request to
  committers to 
  review so they can be auto-merged if possible, otherwise we
  will just 
  manually merge them via cli.  

  Once those are merged, we will work on the plan to merge SPOT-181 into 
  master so that the Open Data Model is consolidated into the main branch of
 
 of our code. 

  We're also working on re-focusing the project release roadmap. Our first 
  step will be to re-engage with the community to better understand 
  how/where 
  Spot is being used today, what features/enhancements would benefit
  the 
  community best, and which committers (existing and potential) are 
  interested in contributing to the roadmap and releases moving forward.

               For graduation it only needs a couple of maintenance releases
               of the remaining code-bases (or not include those in 
               graduation).
               I suggest the project use the next reporting period to

## Toree

Toree provides applications with a mechanism to interactively and remotely
access Apache Spark.

Toree has been incubating since 2015-12-02.

### Three most important unfinished issues to address before graduating:

  1. Active community
  2. Increase active contributors

### Are there any issues that the IPMC or ASF Board need to be aware of?

  None

### How has the community developed since the last report?

  Toree will have a talk at ApacheCon Las Vegas where we will
  talk about its overall status and current functionality as 
  well as try to attract more users and in particular contributors.

  After the release of Toree 0.3.0 the community slowed down,
  mostly due to Toree being somewhat stable and running on top
  of Spark, where the public APIs in use are also stable. 

  The community needs to work on a release that supports Apache
  Spark 2.4.x and Scala 2.12.

  Toree might be one of those low activity projects which have enough
  active PPMCs (see last ppmc voting thread), and we might
  start graduation talks based on these facts.

### How has the project developed since the last report?

  Very little activity on the last few months after the
  Toree 0.3.0 release, mostly around some compatibility
  issues with Spark 2.4.x and Scala 2.12.

     ACNA we will likely shutter the effort.

  Dave Fisher: A similar note was made last year. No trouble if this 
  retires and then returns as an Infra tool.
