B-Trees vs. LSM-Trees: Why your Database choice is actually a Trade-off

Introduction We often treat databases like black boxes. You throw data in, you get data out. But underneath the hood, how that data is physically stored on disk determines if your app scales or crawls. Today, we're looking at the two heavyweights of storage engines: B-Trees and LSM-Trees . 1.
