Web3 Apache Flink guarantee exactly once processing upon failure and recovery by resuming the job from a checkpoint, with the checkpoint being a consistent snapshot of the distributed data stream and operator state ( Chandy-Lamport algorithm for distributed snapshots). This guarantee exactly once upon failover. 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.
