ArangoDB 3.4 GA
Full-text Search, GeoJSON, Streaming & More

00General, ReleasesTags: , , , ,

The ability to see your data from various perspectives is the idea of a multi-model database. Having the freedom to combine these perspectives into a single query is the idea behind native multi-model in ArangoDB. Extending this freedom is the main thought behind the release of ArangoDB 3.4.

We’re always excited to put a new version of ArangoDB out there, but this time it’s something special. This new release includes two huge features: a C++ based full-text search and ranking engine called ArangoSearch; and largely extended capabilities for geospatial queries by integrating Google™ S2 Geometry Library and GeoJSON.  Read more

AWS Neptune: A New Vertex in the Graph World — But Where’s the Edge?

14cluster, General, Graphs, Performance

At AWS Re:Invent just a few days ago, Andy Jassy, the CEO of AWS, unveiled their newest database product offerings: AWS Neptune. It’s a fully managed, graph database which is capable of storing RDF and property graphs. It allows developers access to data via SPARQL or java-based TinkerPop Gremlin. As versatile and as good as this may sound, one has to wonder if another graph database will solve a key problem in modern application development and give Amazon an edge over its competition.

ArangoDB 3.3 Beta Release

01General, ReleasesTags:

It is all about improving replication. ArangoDB 3.3 comes with two new exciting features: data-center to data-center replication for clusters and a much improved active-passive mode for single-servers. ArangoDB 3.3 focuses on replications and improvements in this area and provides a much better user-experience when setting up a resilient single-servers with automatic failover.

This beta release is feature complete and contains stability improvements with regards to the recent milestone 1 and 2 of ArangoDB 3.3. However, it is not meant for production use, yet. We will provide ArangoDB 3.3 GA after extensive internal and external testing of this beta release. Read More

This milestone release contains data-center to data-center replication as an enterprise feature. This is a preview of the upcoming 3.3 release and is not considered production-ready.

In order to prepare for a major disaster, you can setup a backup data center that will take over operations if the primary data center goes down. For a server failure, the resilience features of ArangoDB can be used. Data center to data center is used to handle the failure of a complete data center.

Data is transported between data-centers using a message queue. The current implementation uses Apache Kafka as message queue. Apache Kafka is a commonly used open source message queue which is capable of handling multiple data-centers. However, the ArangoDB replication is not tied to Apache Kafka. We plan to support different message queues systems in the future.

The following contains a high-level description how to setup data-center to data-center replication. Detailed instructions for specific operating systems will follow shortly. Read more

ArangoDB 3.2 GA
RocksDB, Pregel, Fault-Tolerant Foxx & Satellite Collections

00General, ReleasesTags: , , , ,

We are pleased to announce the release of ArangoDB 3.2. Get it here. After an unusually long hackathon, we eliminated two large roadblocks, added a long overdue feature and integrated an interesting new one into this release. Furthermore, we’re proud to report that we increased performance of ArangoDB on average by 35%, while at the same time reduced the memory footprint compared to version 3.1. In combination with a greatly improved cluster management, we think ArangoDB 3.2 is by far our best work. (see release notes for more details)

One key goal of ArangoDB has always been to provide a rock solid platform for building ideas. Our users should always feel safe to try new things with minimal effort by relying on ArangoDB. Todays 3.2 release is an important milestone towards this goal. We’re excited to release such an outstanding product today. Read more

A Reminder on Database Security

01GeneralTags:

With billions of objects and people connected to the internet and your precious data sometimes exposed publicly security is one of the most important topics to discuss. In light of recent ransomware attacks, databases exposed and other breaches we’d like to share a quick reminder on how to secure your ArangoDB environment.

Attacks can be prevented with the security protections built into the product. We strive to prevent possible security issues by giving appropriate reminders in our web console when authentication is disabled:
