Big Data and Hadoop...

In the coming year 2014, which technologies will take off, there is a lot of discussion about Cloud, Mobile, Big Data and Self Service BI. It remains to be seen if Big Data takes the leap in 2014 and see more adoptions of Big Data related technologies. One of the most important aspects to Big data is to understand what Big Data is, where would the technologies be applicable. There is a lot of hype around Hadoop, so it is very important to understand the nature of requirements and then make a decision on whether Hadoop is relevant or not. Please use the following link for a good tutorial on Hadoop and the related tool set. HDFS is not a good fit in situations where there are
1) Lots of small files,
2) Low latency data access
3) Multiple writers.

Hope the readers will find the above video useful. Also there is a another series on big data published by SQL Server Expert and Friend, Pinal Dave in his blog:, it is a 21 part series well researched and presented. Pinal is one of my favorite authors, he was a big part of the reason why I decided to start a blog on SQL Server BI.
