Computers have been invented to compute large amounts of data at very high speed, relative to the human brain speed. In a sense, computers have always been about "big data". Although "big data" is probably more a marketing term than a technical one, we must acknowledge that we are at a threshold where data mining can be done on such amounts that new approaches are emerging.Read More
On Amazon's EC2, using EBS as the backend storage for your application has been the de-facto standard. Using the local storage of an EC2 container is risky: data loss occurs when a container is stopped and it is not replicated by default. As such, people should default to using EBS, which is Amazon's version of a SAN.Read More
The stabilization algorithm - quasardb is a distributed, peer-to-peer database based on the Chord Algorithm. It is actually much more than that, but for the purpose of this post we will focus on the Chord algorithm and one fundamental process: stabilization.Read More
> The issue described in this post has been fixed in quasardb 1.0.1 released today. We strongly encourage our customers to upgrade their clusters. This issue can cause a denial of service if an attacker has access to the network where your quasardb cluster is installed.Read More
There is a lot of code in this post, it will probably not compile "as is" because of missing headers or compiler's incompatibilities. Nevertheless, we made available through our open source initiative the full working library on github. It has been tested on Clang 3.1, gcc 4.6.1 and MSVC 11 on FreeBSD, Linux and Windows.
