Both systems are distributed and designed with fault tolerance in mind. That means Flink processes each event in real-time and provides very low latency. Big Profit Potential. FTP can be used and accessed in all hosts. Advantages of String: String provides us a string library to create string objects which will allow strings to be dynamically allocated and also boundary issues are handled inside class library. Also there are proprietary streaming solutions as well which I did not cover like Google Dataflow. It will continue on other systems in the cluster. Data is always written to WAL first so that Spark will recover it even if it crashes before processing. In a future release, we would like to have access to more features that could be used in a parallel way. You can start with one mutual fund and slowly diversify across funds to build your portfolio. Apache Spark provides in-memory processing of data, thus improves the processing speed. Fault tolerance Flink has an efficient fault tolerance mechanism based on distributed snapshots.
