It has been a while since I actually posted some code here, and I thought that this implementation was quite nice, in that it is simple & works for what it needs to do.
When people first use neo4j they frequently start out by embedding it in a Java application but eventually they want to explore the graph in a more visual way.
A graph can be realized as a tessellated surface. Each vertex (or point) on the surface has a set of neighbors.
neo4j uses Lucene to handle indexing of nodes and relationships in the graph but something that can be a bit confusing at first is how to handle special characters in Lucene queries.
I have finally managed to understand one of the most unusual databases of today, Datomic, and would like to share it with you.
Just to give you some idea, this is sitting on top of RavenDB’s implementation of leveldb. In fact, I have been using this code to test out the leveldb implementation.
There are a number of factors to take into account while developing distributed software systems.
Presto is an ANSI-SQL compatible real-time data warehouse query engine so existing data tools should be working with it unlike Hive which needed special integration . . .
As I mentioned, I run into a very nasty issue with the TPL. I am not sure if it is me doing things wrong, or an actual issue.
Kris Geusebroek gave this 30-minute presentation at NoSQL matters.
If you follow-along on the tech blog you’ve seen the news that we opened our Python driver this week. We’re pretty excited.
This presentation will explain the advantages of graph databases, and how graphs can be used for a number of important functions, including risk management, relationship analysis and the identification of new business opportunities.
Starting with build 2603, we are now considering 2.5 to be a release candidate. It is feature frozen, and only bug fixes are going in.
Jack Norris, CMO of MapR Technologies, presents a 22-minute screencast on MapR's NoSQL and Hadoop solutions for the enterprise.
This presentation by Aaron Morton looks at Apache Cassandra's application to some leading technologies, including Netflix, Twitter, Reddit, and Rackspace.
It appears that in my previous post I have had an issue with how I read the code. In particular, I looked at the commit log and didn’t look at the most recent changes with regards to how HyperLevelDB does the writes . . .
I’m excited to announce that the beta version of pynuodb, the NuoDB Python driver, is now available on Github! You can also sign up to be an official participant in the beta program.
A demo of the new version of the RabbitMQ simulator with support for several exchange types, importing and exporting configuration and more.
Intellipaat presents this 1-hour training course focused on Apache Cassandra.
This presentation from Couchbase covers the main characters of NoSQL databases, as well as the differences between NoSQL and relational databases . . .
The key message of this talk was not a feature comparison of different relational and NoSQL databases, but rather analysis of application of the databases mainly for startups . . .
The idea of this talk is to refresh our graph theory know how, see which technologies and projects are there right now, the state of the art and feature developments within the graph processing area.
The number of companies startups working in the real-time big data space is pretty stunning (including ourselves).
The fun part is that I can easily check just the things that were changed by HyperDex, I don’t need to go read and understand a completely new engine.
Sqoop is a tool for bulk copying data between a relational database like MySQL and HDFS or another Hadoop based data store like Hive or HBase.
