Three most important unfinished issues to address before graduating:

1. Come up with a new name for DLab
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:

• Adams Disturber (Andrii Dumych) Also awaiting for committer Mykola Bodnar, pending account creation. ICLA files are signed off and submitted, waiting for Apache ID to be created.

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.

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 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 )

2. MYRIAD-280: Improve overall stability
3. MYRIAD-279: Reworking a new UI design

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.

How has the community developed since the last report?

We have four active committers (PPMCs) right now. We have 60 users in the dev list and 1171 Twitter account followers. The new cycle of releases and the new ongoing project features (actively working the new committers on it) is a sign of a successful project rebooting.

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.

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.

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 are need of more committers as there are only a couple of active 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 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.

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

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?

None

How has the community developed since the last report?

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
