    JobManager (also called master) is a management node of Flink. It manages all TaskManagers and schedules tasks submitted by users to specific TaskManagers. In high-availability (HA) mode, multiple JobManagers are deployed. Among these JobManagers, one of which is selected as the leader, and the others are standby.

Flink provides the following features:

  • Low latency

    Millisecond-level processing capability.

  • Exactly once

    Asynchronous snapshot mechanism, ensuring that all data is processed only once.
