You may have heard that the JVM team at 10gen is working on a 3.0 version of the Java driver. It's a bigger project than it might seem. Here are some of the really great features that the team is working on to make MongoDB and absolute joy to use with Java.
An in-depth discussion has been going on over at the neo4j google group discussing the merits and issues related to the explicit node identity of the REST API versus Cypher access.
The NoSQL data store Riak does an interesting thing in its documentation. It features technical comparisons to seven different well-known NoSQL databases. It's pretty transparent and refreshing if you ask me.
It's much easier it is to find the the child and parent paths of an object when you transfer your data into neo4j and use the Cypher query language.
Big news from probably one of the biggest news sites out there. The Huffington Post is abandoning its PHP/MySQL stack in favor of newer technologies. One of them was MongoDB. Here's what the author of the post had to say...
MVB Marko Rodriguez recently announced the release of TinkerPop 2.4, which is a bunch of graph database frameworks, algorithm packages, servers, and more. This release was dubbed "Gremlin Without a Cause," and you can see the logo to go with it below (it's the Gremlin logo dressed like James Dean).
Neo4j was implemented to power Postcards, the new interest graph enabled product from popular social publishing platform Squidoo.
Efficient schema design reduces cost and eliminates barriers to scalability. This requires a different approach to data modeling, with a focus on optimizing for usage patterns rather than merely describing objects.
Twitter-Harvest is a Python script that utilizes the Twitter REST API v1.1 to retrieve tweets from a user’s timeline and insert them into a MongoDB database. It takes care of the nitty gritty and allows you to explore what makes MongoDB great.
Previously it was considered good practice to wrap read operations inside a transaction. The 2.0.0-M04 release makes this recommendation mandatory. Cypher got its fair share of changes too.
The 10gen blog announced the release of Mongo-Hadoop 1.1 in a post that recaps the project's progress so far.
DDD isn't well known in Ruby developer circles. Don't discount it. DDD could be a boon to the Ruby community if it gained momentum. See how this sample Ruby on Rails/MongoDB app was built using DDD techniques.
Get the details on the upcoming NuoDB 1.2 release, follow below. No window dressing, just the facts, so read on...
Learn how Riak and fluentd make a powerful combination for log collection and querying. The fluent-plugin-riak library makes it all possible.
I recently discovered that 10gen, in their quest for MongoDB dominance, has made a brilliant move. They offer free online courses, just like you would find on Coursera.org or Udacity! I haven't yet found another open source-focused vendor that has something like this.
The post "Data Types != Schema" is a really interesting post that provides a clear fundamental look at how we define databases, data types, and schema within the context of the fairly unique NoSQL database, HBase.
Redis inventor Salvatore Sanfilippo posted to the Redis google group recently about some changes to the redis-benchmark utility. The tool is, as you would expect, for testing and load simulation.
OrientDB is a Graph Database "on steroids" because it supports concepts taken from both the Document Database and Object-Oriented worlds. So if that sounds intriguing to you, you should check out this introductory series to OrientDB and using graph schema with it.
Andrew Oliver, a regular author over at InfoWorld and occasionally at DZone too, has been using a CRUD application for testing a variety of cutting edge technologies. It's called "Grandma's Address Book," and this week he tried building it with the Neo4j graph database.
There was an interesting semi-debate style article that focused on the two most popular wide-column NoSQL stores, HBase and Cassandra.
The "Babbage" bundle of releases for Spring Data projects is now in the RC1 stage. The developers expect a GA release around the SpringOne conference this year.
Basho developer Andrew Thompson recently posted a proposal on GitHub to rally the community for an upcoming push to add major security features. The post is initially polling for some opinions on Basho's plan to create PostgreSQL-like security features.
What happens when the index is too big to fit on a single node? What happens when replication is needed for availability? How do you give correct answers when the index is partitioned across several nodes? These are the problems of distributed search.
In this post, the author will demonstrate Spring and Hibernate with NuoDB at cloud scale using AWS capabilities (AWS EC2 and CloudFormation).
OrientDB recently hit version 1.5. The open source, document graph database adds new features such as a new paginated local storage engine, a new and more performant Hash Index type, fetch plan support in SQL, and more.
