HBase: Introduction to column oriented databases

by Luis Cipriani

Tech Talk at 22nd GURU (Sao Paulo/Brazil Ruby User Group). February 25th, 2012

Big Data is getting more attention each day, followed by new storage paradigms. This presentation shows a fast intro to HBase, a column oriented database used by Facebook and other big players to store and extract knowledge of high volumes of data.

This year we expect to tell much more about HBase, since we are using it in a project that’s about to be deployed in production. As soon as we got some nice results we will talk about here. Keep tuned.
