Big Data is well known phenomen and frameworks for storing and processing large amount of data, like Apache Hadoop, are well established. However, recent trends in this area require to process the data immediately and provide updates of analyses run on top of the data in real-time. This is usually called Fast Data. The tools for rapid processing of large amount of data which get more and more traction, like Apache Spark and Storm, will be shortly described in this talk. Further approaches how to process data even faster using in-memory data grids will be discussed. The talk will also cover practical example how to store the data in Infinispan and process the data using Apache Spark.
