This webinar from NuoDB explores common reasons that enterprise strategies fail to scale, as well as how to improve performance without resorting to database tricks like sharding.
Andres Taylor, of Neo4j, presents this 1h18m demonstration of how to use the Cypher query language with Neo4j.
In this video, D.K. Panda from Ohio State University presents: Accelerating Big Data with Hadoop (HDFS, MapReduce and HBase) and Memcached.
An April Fools Roundup, Rackspace acquisitions of NoSQL hosters, and NoSQL benchmarking. Plus the Bitcoin surge and the invisible UI concept.
Okay, after spending quite a lot of time digging through the leveldb codebase, and with several years of working with RavenDB . . .
I’ve done a bit of modelling with years and months in neo4j graphs that I’ve worked on previously but I haven’t ever done anything with time so I thought it’d be interesting to have a go with my football graph.
Over the past six months we’ve added a ton of features to VoltDB 3.0. This blog post lists the highlights, but that just scratches the surface . . .
How to query your complex data with Cypher, and an existing dataset. Dataset available here.
Here's a 15-minute presentation by Brent Luehr from the Okanagan Developers Group.
The following is an 8-minute introduction to Riak from Engine Yard, and it is presented by Edward Chiu, a deployment engineer.
Here we are starting to get into the interesting bits. How do we actually write to disk. There are two parts of that. The first part is the log file . . .
Each thrift insert request blocks until data is stored in commit log and memtable - this is all, other operations (like replication) are asynchronous . . .
TuneWiki now stores more than 1,000,000,000 documents for its service in Couchbase, proving once again the scalability and performance you get with Couchbase.
VoltDB 3.0 introduces the use of JSON-encoded columns to allow more flexibility in how you structure and interact with your data.
There's a lot of bad advice out there regarding MongoDB. As I wrote in my last review, even smart sources can encourage risky methods.
NewSQL and NoSQL databases present developers with a new and interesting programming model where there are fewer connections to the database . . .
Today: Mozilla introduces Persona and a web-based Unreal engine, Glass may be born in the USA, the Spamhaus/Cyberbunker showdown escalates, and some puns about floats.
You can read about the theory of Sorted Strings Tables and Memtables here. In this case, what I am interested in is going a bit deeper into the leveldb codebase, and understanding how . . .
Here's a 20-minute tutorial for connecting PHP to MongoDB from XAMPP in Windows 7.
HappyBase is a friendly interface to interact with HBase from Python. It lets you perform basic HBase operations like get, put and scan.
This talk will give an insight view on the construction of structr, including how the project evolved to a spohistocated REST backend framework as well as how they built CMS components.
I got an e-mail last week from three students at Halmstad University doing a three month project on what programmers want in a job, and how companies can attract talented programmers.
The ability to automatically deploy a site on Azure Web Site from TFService is really interesting, but sadly enough there is no out-of-the-box solution to . . .
This is a bit of a side track. One of the things that is quite clear to me when I am reading the leveldb code is that I was never really any good at C++.
Let’s add a couple of performance tests to the mix. We learned about Gatling in a previous blog post, we’re going to use it here again.
