ArangoDB Weekly #30 | New performance results & O’Reilly article

00NewsletterTags:

Maybe you’ve noticed that there was no ArangoDB newsletter last week. So here’s the news of the last two weeks and the announcement that during the summer our NL will be biweekly. 🙂

In the meantime we’ve improved the performance of the shortest path implementation significantly and rerun the Multi-Model performance tests. The article Data modeling with multi-model databases – a use case for multi-model databases – was a huge success on O’Reilly Radar last week, it had the most page views of all Radar articles. It’s worth to read.

Finally, Mesosphere launched it’s SDK and developer program and we are proud to be one of the first partners that integrate into DCOS. Stay tuned, there will be more to come.

Keep an eye on our blog or follow us on Twitter for news about ArangoDB.

ArangoDB Weekly #29 | new Release 2.6.1, updated Benchmark

00NewsletterTags:

This week we published a 2.6.1 maintenance release. A few weeks ago we published a performance comparison. Since it has raised a lost of interest and the discussions around it have led to improvements in all products we’ve updated the benchmark comparison .
In addition we’ve also released a performance comparison between ArangoDB 2.5 and 2.6.
Stay tuned and follow @arangodb for more news.

Dockerizing a Bloom-based Nonces Service in 10 Minutes

00Documentation, FoxxTags:

In this article I want to explain how to setup a nonce-microservice using docker.

Nonce are one-time tokens that are used to ensure that an action can only be taken once. In a project, we needed to ensure that a pay button is only pressed once. Note that nonces are not used to sign requests or identify a user. This is a separate mechanism.

ArangoDB contains a nonce implementation which is a variation of Bloom-filters. It allows to store nearly unlimited nonces within a limited amount of memory. Nonce are allowed to age, that is after an hour they might expire. If there is sufficient interest, I will explain the algorithm implemented in a separate blog post.

How an open-source competitive benchmark helped to improve databases

017General, PerformanceTags: , ,

TL;DR: Our initial benchmark has raised a lot of interest. Initially we wanted to show that multi-model can compete with other solutions. Due to the open and competitive way we have conducted the benchmark, the discussions around it have lead to improvements in all products, better algorithms, faster drivers and better ways to use the databases.

The latest edition of the NoSQL Performance Benchmark (2018) has been released. Please click here

General Setup

From the outset we published all code and data and asked the vendors of all tested products as well as the general public, not only to run the tests on their own machines, but also to suggest improvements in the data models, test code, database configuration, driver usage and server configuration. This lead to a lively discussion, lots of pull requests and even to the release of improved versions of the database products themselves!

This process exceeded all our expectations and is yet another great example of community collaboration not only for fact finding but also for product improvements. Obviously, the same benchmark code will always show slightly different results when run on different hardware, operating systems, network setups and with more or less RAM. Therefore, a reliable result of a benchmark can essentially only be achieved by allowing everybody to run it on their own machines.

The technical setup is described in the above blog post. Let me briefly repeat the key facts.

Meet Patrick, ArangoDB User and Community Contributor

00CommunityTags:

In April 2015, Thomas Pfeiffer, a user experience researcher and active open-source contributor, did an interview with one very active member of the ArangoDB community – J Patrick Davenport from Palatka, FL, USA. The aim was to get an idea about the open-source project ArangoDB as a whole and the development process so far – from the perspective of a developer. This interview first appeared in Thomas Pfeiffer sessellift blog on April 27th.

Thomas: Hi Patrick, to start off, could you tell me a little about yourself (your background, the job in which you’re using ArangoDB, …)?

Patrick: About me: I’m a Solutions Architect, working for my own company, DeusDat Solutions. I’ve been working over 8 years as a software Bob Villa (This Old House, American Reference). My clients call me in to renovate code bases that are near collapse. I’ve improved multiple Fortune 500 company’s core business applications. Recently I designed half to the Medicare Fraud Detection System for the US Government. That was based on Hadoop.

New Release ArangoDB 2.6

04ReleasesTags:

We are proud to announce the latest release of ArangoDB with lot’s of improvements and many new features. ArangoDB 2.6 is available for download for many different operating systems. In the new release the focus is on performance improvements. For instance sorting on a string attribute is up to 3 times faster. There are also improvements in the shortest-path implementation and other graph related AQL queries.

Look at some of our previous blogposts like: Reusable Foxx Apps with Configurations, Document your Foxx Apps with Swagger 2 or the Improved System User Authentication to learn more about ArangoDB 2.6 and check the manual for a deeper dive into specific features.

Claudius, CEO: “The performance improvements in every area of ArangoDB 2.6 make ArangoDB an effective alternative to other databases. I am very proud of the product and the team, and we can expect much more in the next few months.”
