Apache Flink

Apache Flink is an open-source framework and distributed processing engine for stateful computations over unbounded and bounded data streams. It is designed to run in all common cluster environments and to perform computations at in-memory speed and at any scale. Flink exposes a REST API on the JobManager Dispatcher that allows external systems to query cluster status, submit and manage jobs, trigger savepoints and checkpoints, upload and run JARs, and inspect metrics, accumulators, and exception histories. The same REST endpoints power the Flink Web UI.

    name: Apache Flink REST API
    description: >-
      The Flink REST API is exposed by the JobManager Dispatcher and provides
      monitoring and management capabilities for a Flink cluster. It covers
      cluster configuration, JobManager environment and metrics, job lifecycle
      (submit, list, cancel, stop), checkpoint and savepoint management, JAR
      upload and execution, dataset operations, and TaskManager inspection.
      The same REST API powers the Flink Web UI and is the primary
      programmatic interface for operating a Flink cluster.
