The Secret Life of Data - Part 1
summary
Defines Big Data as datasets too large for sequential processing, requiring MapReduce–style parallelism and cheap storage to save everything for later analysis. Claims the only consistently working commercial use so far is retargeting: AdExtent builds a system that predicts a user’s purchase probability after leaving a site and uses that to bid on ads. Gives surprising correlations — Mac users seeing higher Orbitz prices, local weather sites predicting weight-loss buyers — and cites fraud detection on Amazon Web Services as a clear non-marketing win.
