In this video from the RavenDB Conference, RavenDB creator and Hibernating Rhinos founder Oren Eini discusses the new features of RavenDB 3.0.
Neo4j makes it easy to model connectedness like device usage and management, as well as location, in the same context as data that makes today's applications rich. To demonstrate, we asked GraphAlchemist to build an IoT demo to illustrate the use of graphs with wearables and other connected devices.
We’re happy to announce the update to our Couchbase Plug-in for ElasticSearch. Plug-in is now updated to work with latest release of Couchbase Server 2.5.1 and Elasticsearch 1.0.1.
In this tutorial we'll create a 3-node cluster, where the first serves as a primary node, the second as a failover node, and the third as an Arbiter.
Couchbase includes a TTL (Time To Live) as part of the meta data fields for each document. What if the high performance and flexibility of Couchbase Server were leveraged to provide callbacks for document expiration? Introducing "expiry-notifier" from Couchbase Labs.
In this video, Dan Bishop is talking about high scalability RavenDB, and he is one of the guys behind RavenHQ, so he should know.
Recently, Mongoose 3.8.9 was (finally) released. This was primarily a maintenance release, the major priority was to clean up several test failures against the new stable version of the MongoDB server, 2.6.x, without any backward-breaking API changes.
Recently, Hacker News user roryhughes ran a poll asking what database Hacker News readers (or their companies) use. While the sample size may not be the largest, and "Hacker News readers" is probably not a perfect cross-section of the development world, it's an interesting look at what people are actually using.
In this video from the RavenDB Conference, Matt Johnson talks about how you can extend RavenDB client and server side.
The author used MongoDB as the primary data source in Likeastore and went the way of MongoDB Full Text Search. Everything was fine initially, but after a while it became obvious that MongoDB FTS could not satisfy him any more.
Is data in MongoDB consistent? Is data in Couchbase Server consistent? In this article, the author compares data consistency in two NoSQL solutions, diagramming the structure of each.
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 the ups and downs of migrating from Redis to MongoDB, a look at how to harness Wikipedia's location data with MongoDB, modeling tricks from the RavenDB Conference videos, and more.
MongoDB users: do you have a way to tell how much memory each collection is using? For the Wish Engineering team, the answer was "no," and that's why they developed MongoMem, which allows MongoDB developers to precisely locate collections in need of memory-use optimization.
Cloudera and MongoDB released an interesting press release this week where they aim to continue to work closely together. Is this AGoodThing[™]? The author discusses here.
This post is a recap of the second day of Hbase from the Seven Databases in Seven Weeks book. The first thing the author had to do in day two was download lots of data (big data) and stream it into Hbase, and then customize a JRuby script.
In this video from the RavenDB Conference, Mauro Servienti takes a look at RavenDB, CQRS and EventSourcing.
If the Internet of Everything will read and write to NoSQL databases, do they need to support communication over MQTT / CoAP? What if they did? What would the enterprise architecture look like, and what would be the impact?
With neo4j.com, we’re collecting everything you need to know in one place. We’re pulling in written content from many sources, including neo4j.org, neotechnology.com, docs.neo4j.org and blog.neo4j.org.
In this article, Kijana Woodard discusses messaging with RavenDB in this talk - his second ever! - from the RavenDB Conference.
About 6 months ago we looked at how to translate a few lines of Cypher in to way too much Java code in version 1.9.x. Since then Cypher has changed, and the author sucks a little less at Java, so he wanted to share a few different ways to translate one into the other.
At long last, we present the official Developer Preview 1 (DP1) for the Couchbase .NET 2.0 SDK! This DP1 represents the minimal subset of features promised and should give you a feel for the direction we are taking the API from a developer’s perspective.
There is a lot of information on Wikipedia - basically all the information there is, right? - but one particularly interesting bit of data that can be pulled from Wikipedia articles is location data. And when you have a boatload of data with no real purpose, what do you do with it? Put it into MongoDB, of course.
New Relic has become an industry standard for web application performance measurement. With Kurobase releasing a new-relic add-on for Couchbase on the heroku platform, developers can have really good analysis and optimization tools at their disposal.
In this article, you'll find David Boike's presentation from the RavenDB Conference titled "Modeling Tricks my Relational Database Never Taught Me."
Often, migrating your database to MongoDB is a SQL vs. NoSQL situation, but when it's NoSQL to NoSQL, it can be a bit more nuanced. This recent post from Lee Kimber on Rackspace's blog explores a client's migration from Redis to MongoDB, and it's a bit more even-handed than most.
