Big Data hasn't been about storage, I thought it was always about processing. Guy obviously knows his stuff but I got the impression he stressed more about storage and how that's cheap and easy these days. When he does mention processing/computing, he mentions that most of the time people end up only querying recent data (ie small chunk of actual data they hold) but that bears the question: is querying only small chunk of data what businesses need, or are they doing it because querying the whole dataset is just not manageable? In other words, if processing all data at once was as easy as querying the most recent X percent, would most businesses still choose to only query the small chunk? I think there lies the answer whether Big Data (processing) is needed or not.
