Hadoop - a Big Data Sneak Peek
What is Hadoop ? According to the Apache website Hadoop . It is a software library framework that allows distributed processing of large datasets across clusters of computers using simple programming models. So How's Hadoop different than regular DBMS ? Current DBMS can store large datasets in clustered settings but what sets Hadoop apart than regular DBMS systems ?(e.g. Oracle). Aren't we storing large datasets in the database system and can access them using simple programming models ? The answer to that is BIGDATA. Right now as software systems mature and more complex ones are created organizations are having a hard time storing, managing and analyze the data that they have. So what differentiates BIGDATA from just data. The 3 V's Velocity - Velocity is the rate at which how an organizations data grows. Data grows really fast. For example Google processes about 24 petabytes per day ( ACM White Paper - MapReduce ) Variety - Data comes f
