CUBA Scheduled Tasks

CUBA scheduled tasks mechanism is intended to perform scheduled execution of arbitrary Spring beans methods on Middleware. The purposes of this mechanism and its distinction from the above mentioned standard Spring Framework schedulers are:

  • The ability to configure tasks while running an application without restarting the server.

  • The coordination of singleton tasks in the Middleware cluster, including:

    • Reliable protection from simultaneous execution.

    • Binding tasks to servers by priorities.

A singleton task is a task which must be executed only on one server at a certain moment of time. For example, reading from a queue and sending emails.
