=== Spark vs MapReduce ===
=== Finance and Stock trading Use Case ===
Imagine that you are working for a financial company and your job is to buy in and buy out stocks to make money. The decision you make highly depends on the prediction which is calculated by your financial model. In this kind of situation, how long it takes for your financial model to make a prediction is very critical. We know that the price of stocks change very fast. In a couple seconds a stock can change prices drastically. Thus, if your model cannot provide you a near real time response, you might lose your opportunity to trade your stocks with the best price. Apache Spark can be utilized to create financial models to make predictions in real time.
