The ArangoDB team is back from holidays, wishing you and your families a happy New Year 2015. This year will become a good one for multi-model databases – like ArangoDB – according to analysts, quoted in the NoSQL trends 2015 article from Dataversity. This newsletter covers the last 3 weeks, including the beta of ArangoDB 2.4, build on christmas eve.

There is a warm-up routine on every evening at the NYC Database Month. Speakers ask trivia questions to the auditorium, related to the topic of the following talk. The first correct answer wins some “swag”. On Tuesday, Nov. 11, 2014 Max from ArangoDB will talk about Polyglot Persistence and multi-model NoSQL databases.

Like every year, the ArangoDB team visited the FrOSCon. FrOSCon is the yearly Free and Open Source conference in St. Augustin, a small city near Cologne where the ArangoDB headquarters are. This year two talks were given by us, one by Michael and one by me, Lucas.

Michael gave a talk about “Multi-Model NoSQL Databases” and gave an introduction to Polyglot persistence and NoSQL. He also co-organized the JavaScript track of the conference with topics ranging from Angular JS to Property-based testing.If you missed his talk, you can watch it here:

Lucas (@moonbeamlabs), ArangoDB core developer, rubyist, inventor of Foxx, open source contributor, podcaster etc. – he is currently staying in Mountain View. Yesterday he spoke at the SF JavaScript Meetup at Mozilla and did an introduction to ArangoDB Foxx. Tomorrow he will give a lightening talk about Guacamole at the San Francisco Ruby on Rails Group.

In Next gen NoSQL: The demise of eventual consistency a recent post on Gigaom FoundationDB founder Dave Rosenthal proclaims the demise of eventual consistency. He argues that Google Spanner “demonstrates the falsity of a trade-off between strong consistency and high availability”. In this article I show that Google Spanner does not disprove CAP, but rather chooses one of many possible compromises between total consistency and total availability. For organizations with a less potent infrastructure than Google other compromises might be more suitable, and therefore eventual consistency is still..

FOSDEM is an absolutely open and free conference in Brussels, Belgium. The conference offers an impressive amount of developer rooms discussing a broad range of technical topics, including NoSQL and graphs.

After a funny and productive ArangoDB hackathon weekend Frank and I arrived at FOSDEM on Sunday noon. We were looking forward to the talks in the graph devroom, but unfortunately for us it was not possible to enter the room (it was overfull, indicating a great quality of talks).At the next speakers change Frank and I managed to slip into the room and could enjoy two inspiring talks by..

RubyConf is a yearly conference in the USA with people coming from all over the world to discuss about Ruby, Rails and related topics. Every year a different city hosts this conference – this year the conference took place in sunny Miami Beach. This year Dirk Breuer – the other main developer behind Guacamole – and I went there to learn from the speakers talking about a wide range of topics. Apart from the great talks there was a lot of opportunity to talk to Rubyists from entirely different areas like social networks or banking backend systems, the problems they face and the solutions they..

The ArangoDB team traveled to Barcelona for the “NoSQL matters” – weekend. Day one was packed with a lot of NoSQL-trainings and Jan introduced the NoSQL landscape by explaining how to model your data in a non-relational world. Following the wish of many participants Jan had to repeat the morning session about the new and exciting possibilities of NoSQL in the afternoon.
