Aurelius Annoucement

[Matthias Broecheler]

Hello everybody,

I am very excited to announce that Aurelius has been acquired by DataStax which marks a great milestone for graph database technology.

When Marko started Aurelius some three and a half years ago, graph databases were still in their infancy. When I joined him a year later and we started the Titan project, graph databases weren't supposed to scale as vendors explained that this technology was meant for complex but small data sets. We built a graph database platform that proved them wrong and in the process pioneered many of the concepts needed to achieve scale: vertex-centric indexes, efficient graph partitioning through edge- and vertex-cuts, distributed vertex id allocation, and others. These ideas are finding their way into other products and will hopefully advance the state of the art in graph database technology.

Despite its immaturity, Titan was warmly welcomed by the open source community. Over the years, Titan was deployed in a number of interesting use cases, offering a first glimpse at the possible applications that a scalable graph database could enable. We are incredibly enthusiastic about those use cases and thankful for all the insightful feedback we have received.

An increasing number of companies have contacted us with their production support needs for mission critical applications. Hence, we decided it is time to take it to the next level and build a commercial, enterprise-ready, scalable graph database. We will be doing so as part of DataStax and on top of the DataStax Enterprise (DSE) platform, which is their commercial Cassandra offering.

For technological and ideological reasons it makes a lot of sense to join forces with DataStax.

In our development of Titan, we relied on existing storage systems as a backing store rather than reinvent the wheel. Through this experience and our work with customers we have become increasingly fond of Apache Cassandra as a distributed datastore technology that lives up to its promise of scaling out and beyond data centers. Hence, we believe that DSE is the strongest platform on which to build a massively scalable graph database. By tightly integrating with the storage layer, we will be able to achieve higher performance and better usability.

In addition, DataStax shares our vision for graph databases and is equally driven to advance the graph community and expand the market. DataStax, with a proven track record of open source contributions in Apache Cassandra, is committed to furthering TinkerPop which was recently incubated with Apache and will dedicate significant resources to its continued development.

However, there is also some sadness in this announcement. As we transition to DataStax, we will find little time to contribute to Titan and interact with the Titan community. We will miss that and hope that it will be carried forward.

The graph community just got a big boost and we are very honored to be part of it. We will keep you posted as we get started on building the next-generation graph database with DataStax. Please contact us with any questions or comments.

Cheers,

Matthias

If you all can no longer maintain titan, will you delegate the responsibility of reviewing and accepting patches, and possibility creating releases, to a community member?

Congratulations on taking your organization to the next level.

Very interesting indeed! We're at the start of a development cycle and were considering titan as an option. Will the DataStax Graph system be compatible with Gremlin+Rexster and the like? In which case we could continue with our plans and migrate to DS-Graph when its rolled out.

Are we going to at least get this to 0.9 first or is it going to die as is pre 0.9 GA?

[Brian O'Neill]

Likewise, let me offer my congratulations.  Although we don't use DSE, we are big fans of Datastax.

We are using Titan extensively.

Let me know if we can help out with ownership/transition to community members.

Congratulations Team Aurelius.

How about giving it to Apache Incubation like Tinkerpop? That would really put impetus to its further development.

Best Regards,

Deepak

A bit upset at first but after a bit it started to sink in.

I'm thankful and appreciative for all the work you guys have put into Titan so far.

I understand the decision though I always believed you could do, and be, so much more on your own.

I hope you make the right decision with regards to the future of open-source Titan. Would love to continue using, and hopefully contribute to, it.

I didn't want to respond to each thread individually, so I created a new one to summarize:

Thanks a ton..
Ray of hope er...peace of mind to titan lovers..

Wish you success with DSE Graph. Do share some of its features with titan too :) in future..

Thanks,
Deepak
