I am in complete awe on how this technology is resonating with today’s developers. If I invite developers for an evening event, Big Data is always a sellout. This particular post is about getting everyone up to speed about what Hadoop is at a high level. Big data is a technology that manages voluminous amount of unstructured and semi-structured data. Due to its size and semi-structured nature, it is inappropriate for relational databases for analysis. Big data is generally in the petabytes and exabytes of data.
