“It is often thought that Apache Hadoop based data lakes are a potential panacea to thorny data management issues long germane to relational databases. After all, the (mistaken) belief goes, you can simply dump all your data into Hadoop’s file system, and via schema on read magic, your desired result sets will appear with very little effort. However, data management—even for Hadoop—isn’t going away and in fact, probably never will.” Paul Barsch ( February 23, 2015 )
