this covers taking your first steps with two big data applicationshadoop and spark using python to write big data jobs building an interactive dashboard that connects to data stored in big data database over the last two we've steadily increased the size of the data in we worked with data sets that could fit into the main memory of computer introduced techniques to deal with data sets that were too large to fit in memory but could still be processed on single computer in this you'll learn to work with technologies that can handle data that' so large single node (computerno longer suffices in fact it may not even fit on hundred computers now that' challengeisn' itwe'll stay as close as possible to the way of working from the previous the focus is on giving you the confidence to work on big data platform to do thisthe main part of this is case study you'll create dashboard that allows
