Flink topology
Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale. Here, we explain important … See more Any kind of data is produced as a stream of events. Credit card transactions, sensor measurements, machine logs, or user interactions on a … See more Flink is designed to run stateful streaming applications at any scale. Applications are parallelized into possibly thousands of tasks that are distributed and concurrently executed in a cluster. … See more Apache Flink is a distributed system and requires compute resources in order to execute applications. Flink integrates with all common cluster resource managers such as Hadoop YARN, Apache Mesos, and Kubernetesbut … See more Stateful Flink applications are optimized for local state access. Task state is always maintained in memory or, if the state size exceeds the available memory, in access-efficient on-disk data … See more WebFew of them provide adequate supports to adapt the topologies of stream processing tasks to changing input workload. We present an intelligent and efficient topology adjustment scheme which allow Flink framework to refine its topology on the basis of incoming workload. It is designed to increase the overall performance by making the refining of ...
