Stacks 317. Pros of Apache Flink. Apache Spark exécute des itérations en déroulant une boucle. Next steps. Flink has been compared to Spark, which, as I see it, is the wrong comparison because it compares a windowed event processing system against micro-batching; Similarly, it does not make that much sense to me to compare Flink to Samza.In both cases it compares a real-time vs. a batched event processing strategy, even if at a smaller "scale" in the case of Samza. Add tool. It’s by no means a comprehensive list - there are many more streaming systems out there, but these seem to be quite popular. The Flink Kafka Consumer allows configuring the behaviour of how offsets are committed back to Kafka brokers.
