Don't use Hadoop when your data isn't that big
Hooray! Some sense at last.I have worked for at least 3 different employers that claimed to be using "Big Data". Only one of them was really telling the truth.All of them wanted to feel like they were doing something special.The sad thing is, they were all special, each in their own particular way, but none of what made each company magic and special had anything to do with the size of the data that they were handling.Hadoop was required in exactly zero of these cases.Funnily enough, after I left one of them, they started to build lots of Hadoop-based systems for reasons which, as far as I could fathom, had more to do with the resumes of the engineers involved than the actual technical merits of the case.Sad, but 'tis the way of the world.
