Incubation at Apache

[Jason Plurad]

Titan 1.0 was released one year ago. Happy Birthday, Titan!

Over the past year,

• Apache TinkerPop graduated to a top level project
• Amazon emerged with DynamoDB support for Titan
• Classmethod emerged with Tupl support for Titan
• IBM Graph emerged with graph database as a service using Titan
• ScyllaDB emerged with Thrift support for Titan
• DataStax Enterprise Graph launched as a "Titan-inspired" product

Even without an official Titan release in the past year, community interest in Titan has continued:

• 2,500+ emails on this mailing list
• 1,000+ stars added on GitHub, now at 3,965
• 100+ commits on titan11 branch
• 37 open pull requests waiting for review/integration

I gave a Titan talk earlier this month at Scylla Summit and attended the Cassandra Summit. At both events, I was fortunate to meet with many other developers who were interested in contributing to Titan as an open project with open governance.

We've seen people mistakenly describing Titan as "Apache Titan". We've seen folks on mailing lists asking if taking Titan to Apache would be a possibility. Titan is a missing piece at the ASF in its big data graph architecture. If you use Titan already, you know the list: Apache TinkerPop, Apache Cassandra, Apache HBase (and Apache Zookeeper), Apache Lucene, Apache Solr, Apache Spark, Apache Giraph, and Apache Hadoop.

Many thanks go to Matthias and Dan for Titan, a boon to the open source graph community. Now, this community needs to move Titan forward. If you are interested in contributing to Titan and taking an incubation proposal to Apache, please respond to this thread.

There's cake for everybody. Grab a fork.

Happy birthday Titan! Thank you for everything that you have done for us!

Now let's move on to the next steps! :)

Happy Birthday, Titan!

We are happy to join the proposal to take Titan to the Apache Incubator.

Happy birthday Titan! Incubating at Apache would make total sense, I'd love to help out!

[Haikal Pribadi]

Hi everyone,

We're very excited to see Titan being pushed forward for Apache Incubation. Over the past year, MindmapsDB has also emerged as an open-source semantic graph database built with Titan. There needs to be a leading open-source graph database in the industry, as well as the reference implementation for Apache Tinkerpop. So needless to say, our team and MindmapsDB are fully supporting and will contribute to Titan's development.

Cheers,

Haikal

Titan is one year wiser now, happy birthday Titan.

Everything is moving forward and we cannot leave Titan behind. Let's move forward.

[Filipe Peliz Pinto Teixeira]

Hi All,

I would be very happy to help with Titan becoming Apache incubated. Myself and my colleagues have been using Titan for almost a year in developing our own Semantic Graph Database https://mindmaps.io/ . I have also taken a personal liking to it and would love to see its continued success and development. The open source graph community needs a Titan :) 

Thanks to Jason for putting this idea forward.

Regard,

Filipe

Happy Birthday Titan!

Very excited to see Titan entering the Apache fold. With all the progress and interest that has built up since 1.0, the incubator boost is set to cement Titan's place among the pantheon of go-to graph computing options. Thanks to the Aurelius and TinkerPop teams, and the Titan community for bringing Titan into its own (especially Jason for getting the incubation process rolling)  - looking forward to the next evolution!

At my company (Expero) we keep seeing Titan at our customers. We already participate in TinkerPop, and would love to contribute to Titan as well.  We have also considered offering commercial Titan support.

[Palash Kulshrestha]

Happy birthday titan. It's incubation in apache would be a perfect gift.

[hmar...@slb.com]

Congrats! Moving Titan to Apache incubation is a great idea and a logical next step!

Happy birthday Titan and thanks to everyone who contributed to it!

It would be really great to see Titan becoming an Apache project :-)

[kpa...@slb.com]

This certainly would be great for us.   The TitanDB is better than many other graph databases we have tried. 

thanks

We've made great use of Titan here at OpenDNS and are interested in
seeing it continue to move forward, so you can count me in on this.

[Henry Saputra]

Been wanted to see this in ASF to get more adopters and contributions. Thank you for starting the discussions =)

Please let me know if it is Ok for me to help champion this project to ASF incubator.

We're using Titan to drive academic research of cancer biology, and we would love to see it move forward as an Apache project.

While I probably don't have a sufficient developer skill set to contribute code, I can definitely help with the process and usage from an end user perspective. This is a missing feature to the ASF stack and I support it 100%.

[王斌]

Happy to contribute.

[Austin Sharp]

I would love to see Titan move into the ASF and would hope to contribute as well!

Hello All,

I just saw https://s2graph.apache.org/ and I am wondering where Titan (after moving to Apache ) would stand in the overall ecosystem/scheme of things.  Pardon my ignorance but the question I have is "Is Titan already approved for Apache Incubation status or we are in the process of getting the approval ? " S2Graph seems to be an Apache project already and am not sure about the Tinkerpop integration / Companies using S2Graph etc. 

Regards,

Ananth

A proposal has been submitted to the Apache Incubator. You can find details on this discussion thread: https://lists.apache.org/thread.html/a0fb590f0ea2d29ffcbbe6f6f1cdd025a511551ce8460f57c4eee897@%3Cgeneral.incubator.apache.org%3E

Please feel free to express your feedback.

You can read more about the incubation process here. http://incubator.apache.org/incubation/Process_Description.html

TL;DR proposal first, then a discussion on the mailing list, then a vote to accept into the incubator. The whole process takes a week or two.

The proposal mentions S2Graph which has been incubating since last year. As far as I'm aware, the S2Graph community is smaller, and they are still trying to push out their first incubation release. S2Graph is written in Scala. It is well adopted at Kakao, where the project originated, across different services.

S2Graph does not implement the TinkerPop APIs and Gremlin. I met with them at Apachecon earlier this year and had a good chat with them trying to convince them to do so.
https://issues.apache.org/jira/plugins/servlet/mobile#issue/S2GRAPH-72

There is some overlap between Titan and S2Graph in that they are both property graph database systems, but there are other examples of Apache projects with similar capabilities. Cassandra and HBase come to mind as BigTable-inspired database systems.

Apache is all about building community over code, and that's what I hope folks on this thread are excited about doing for Titan (to be renamed).

Thanks for providing the additional context Jason.

It looks like we wait for a few more weeks before the "legal issues" are sorted out as per the thread below.

Looks like DataStax has responded: https://lists.apache.org/thread.html/e4f2c1403bfb4fe75fce9bd6f3182b9a95b9830ad9893944bac01ed9@%3Cgeneral.incubator.apache.org%3E

Quote:

Hello - my name is Jason Anderson with the DataStax legal group. On behalf of DataStax, I wanted to clarify any potential confusion regarding the DataStax position on Titan. As several posts here have explained, DataStax owns the copyright and trademark rights to Titan. DataStax does not approve of and objects to the proposed forking of Titan into Olympian or any other ASF project. DataStax is evaluating the path forward for the Titan project and considering the various go-forward licensing options. Titan may or may not stay ASL 2.0 licensed as there may be potentially broader benefits to the community with GPL or A-GPL. At this time, we do not have a timetable on these decisions but will provide more details to the community when possible.  Jason

So it would seem that DataStax is hostile to the idea. Thats a shame. Given that development has effectively stopped 8 months ago (?), the last pull request merge was 3 months ago and they are hostile to moving the code to a community driven project, we may need to start looking somewhere else.

"Titan may or may not stay ASL 2.0 licensed as there may be potentially broader benefits to the community with GPL or A-GPL"

are they hinting at the nasty dual license thing that oracle does with mysql?

Hello
         I was following this discussion, from what i read Datastax does not want Titan to be taken forward by the open source community and so Titan cant/wont be part of ASF. Does that mean its the end of the road for Titan ( for the open source community i mean)?

Any updates on this topic?

Regards

[Misha Brukman]

Hi Ajay,

Taking Titan to the ASF Incubation was certainly the preferred option, but is not the only option. We are still working on the next steps for the project and will come back with a new proposal for the community to review soon.

Hi Tom,

No worries, we understand the concern — apologies that it's taking so long, we are still working out some non-technical issues that are taking a bit longer than expected. We hope to have a more concrete update within a few weeks.

Thank you for your patience!
