Traditional relational databases are built upon a synchronous, client-server architecture that is often limited in terms of scalability requirements that are posed by distributed computing systems.
In leveldb we have the memtable, into which all of the current writes are going and the immutable memtable. So far, I haven't really checked what it actually means.
The term "NoSQL" defines a wide range of database technologies that offer alternatives to the traditional RDBMS.
This video from ZeroToProTraining.com explores differences between RDMBS and MongoDB, while also providing an overview of NoSQL solutions.
Enjoy this preview milestone! Use the Neo4j Google Group to tell the Neo4j team and other members of the Neo4j community what you think.
This is something that every dev and app that stores data has had to deal with, updates and changes over time . . .
After figuring out how the TableCache works, I now want to dig a bit deeper into what the Tables are. That means that we are starting out in Table::Open. And this starts with:
Struts 1.x reaches its end of life, Neo4j reaches a new milestone, a .pdf to .csv data extractor, and Zen koans . . . for Git. Click through for links you don't want to miss.
Running on a suitable EC2 configuration (see details below), with our new VoltDB Erlang driver we achieved 877,519 transactions per second.
In the previous post, I focused mostly on reading the code for writing a SST to disk. But I have to admit that I am not really following how you read them back in a way that would be easy to read.
Intro to MapReduce concepts. Explores the flow of a MapReduce program.
If you've been following this blog for any length of time, you know that my NoSQL database of choice is MongoDB. One thing that MongoDB isn't known for, however, is building a publish / subscribe system.
The Normalisation is a data analysis technique to design a database system. The Normalisation allows the database designer to understand the current data structure within an organisation.
Here's an interview with Michael Stonebraker of VoltDB from Big Data Cloud back in January.
The phrase "unit testing" evokes a wide variety of opinions within the developer community. At this point, most individuals understand the concept through direct experience or . . .
Here's a 30-minute introduction to Big Data and Hadoop from Edureka.
I wonder why more open source users do not actively participate in the open source community and become committers or contributors.
After going over the VersionSet, I understand how leveldb decide when to compact and what it decide to compact.
For this post, I want to see where continuing to read the Version code will take us.
Titan is a distributed graph database capable of storing graphs on the order of hundreds of billions of edges while, at the same time, supporting billions of real-time graph traversals a day.
Riak is one of the new breed of no-SQL database management systems, which has begun to replace relational databases for some applications.
In 20 minutes, this tutorial will get you started with Oracle NoSQL Database. You will install the product, learn common terminology and learn about the flexible options for Durability and Consistency.
We are proud to announce this year’s NoSQL Roadshows designed for everyone who is interested in faster and cheaper solutions to managing fast growing databases and data stores. This year the program is divided into two tracks targeted developers and...
This video introduces you to the basic concepts of graph theory by working through a sample question.
I have talked about human filters and my plan for digital curation. These items are the fruits of those ideas, the items I deemed worthy from my Google Reader feeds.
