(2) An open source big data framework from the Apache Software Foundation. Spark is used to analyze huge amounts of real-time data in RAM in contrast to Hadoop (another Apache project), which continuously writes to the storage drive. As a result, Spark is generally many times faster. Because Spark does not have its own distributed file system, it is often used in conjunction with the Hadoop Distributed File System. See
