With the release of Neo4j 2.1 we can now make use of Ronja – the experimental Cypher optimiser – which performs much better for certain types of queries. I thought I’d give it a try.
This talk from Itamar Haber, Chief Developers Advocate at Redis Labs, took place at DevconTLV and provides an introduction to Redis use patterns, particularly compared to a relational perspective.
I’ve been slowly (oh so sloooowwwwly) working on MLJS since my last release in April. Going to try to do smaller, more frequent releases in the future. Done some cool stuff for demos and my other pre-sales colleagues in MarkLogic – all based on real world customer requirements.
On behalf of the whole SDK team I'm glad to announce the second developer preview of the Java/JVM SDK release train nicknamed Armstrong. It currently contains both the JVM core package "core-io" 0.2 as well as the Java SDK 2.0 preview 2.
One of the points that I emphasised during my talk on building Neo4j backed applications using Clojure last week is understanding when to use Cypher to solve a problem and when to use the programming language. A good example of this is in the meetup application I’ve been working on.
This blog post presents rolling time window counting and rate limiting in Redis. You can apply it to activate login CAPTCHA on your site only when it is needed.
Yesterday I released version 0.3.1 of Motor, the asynchronous MongoDB driver for Python and Tornado. This release is compatible with MongoDB 2.2, 2.4, and 2.6. It requires PyMongo 2.7.1.
The Neo4j community once again posted tons graph-tastic stuff this past month from awesome articles to great GraphGists. Here are a few of our favorites from the Neo4j community in June:
Cassandra has numerous built-in data types, but there are situations in which one may want to add a custom type.
In the 2.6 release, MongoDB made a subtle but significant change in the way the underlying aggregation pipelines execute in a sharded environment.
When our friends over at Treasure Data wrote to me about Fluentd, an open-source logging daemon written in Ruby that they created and maintain, I immediately saw value for MongoDB users looking for a quick way to collect data streams and store information in MongoDB.
NoSQL is big business, but according to John A De Goes, it has a fatal flaw in its lack of analytics tooling. Given that SQL is working to incorporate some of the advantages of NoSQL, what will happen as the divide between the two becomes narrower?
Recently Google, MongoDB Inc., and MongoLab announced the arrival of fully-managed, production-ready MongoDB replica set plans on the Google Cloud Platform (GCP). These plans are hosted on Google Compute Engine (GCE) and managed by MongoLab.
Make sure you didn't miss anything with this list of the Best of the Week in the NoSQL Zone. This week's best include a look at updating documents in MongoDB and R, why shared storage hinders performance in Cassandra, a report from MongoDB World 2014 in NYC, and more.
Today we released a minor version of the .NET 1.X SDK: 1.3.7. This was a very small bug fix release and featured some contribitions from the community. A big thank you to the individuals who contributed and/or took the time to fill out a bug report or request a feature!
The ArangoDB 2.2.0 beta has been released! We covered ArangoDB a while back, and the NoSQL database has been steadily improving since then. According to Frank Celler's release announcement, this most recent release covers a wide variety of bug fixes and changes, but focuses on three major items.
In a word ladder puzzle you must make the change occur gradually by changing one letter at a time. At each step you must transform one word into another word, you are not allowed to transform a word into a non-word. See how to neatly implement this using Neo4j.
The cloud is the new operating system, and projects like Apache Brooklyn enable the enterprise to be more efficient. What if you could deploy a dozen instances of Couchbase Server to Amazon Web Servers with the click of a button?
Closely approaching the one year mark of when I first joined MongoLab (and the MongoDB community), I had the pleasure of attending the inaugural MongoDB World conference put together by the incredible MongoDB team. There was a lot to digest from the conference... here are the major highlights.
The author was recently asked how to find the number of movies produced per decade in the movie data set that comes with the Neo4j browser. In this article, you'll find out how.
In a recent MongoDB and R project, the author faced a new problem. He was using R to process source data present in MongoDB, and if he gave a large number of documents to R for analysis, it was becoming slower and a bottleneck.
Since version 2.1, Neo4j provides out-of-the box support for CSV ingestion. But hear my words of advice before you jump directly into using it. There are some tweaks and configuration aspects that you should know to be successful on the first run.
One question that keeps coming up, according to Jonathan Lacefield, is why shared storage is not recommended for Cassandra. The short version? Performance suffers, and it introduces a single point of failure. Lacefield's explanation, however, aims to clarify what "performance suffers" really means.
UbiGraph is a graph rendering server that is controlled remotely and also interactively with a XML-RPC API (which is a weird choice). It comes with example clients in Java, Python, Ruby and C. In this article, you'll learn the basics of UbiGraph and how to render Neo4j with it.
Make sure you didn't miss anything with this list of the Best of the Week in the NoSQL Zone. This week's best include a look at performing CRUD operations on MongoDB in a Node.js app, the need for DBaaS in the app economy, and thoughts on how to control an ever-expanding MongoDB database.
