Stateful Stream Processing Apache Flink

WebIn this tutorial, we will discuss the comparison between Apache Spark and Apache Flink. Apache spark and Apache Flink both are open source platform for the batch processing as well as the stream processing at the massive scale which provides fault-tolerance and data-distribution for distributed computations. WebApache Flink’s snapshot algorithm is based on a technique that was introduced in 1985 by Chandy and Lamport, to draw consistent snapshots of the current state of a distributed system without missing information and without recording duplicates. WebThese operations are called stateful. When an application searches for certain event patterns, the state will store the sequence of events encountered so far.
