Public Methods

public abstract boolean prefersShortLivedTasks ()

Does this TaskExecutor prefer short-lived tasks over long-lived tasks?

A SchedulingTaskExecutor implementation can indicate whether it prefers submitted tasks to perform as little work as they can within a single task execution. For example, submitted tasks might break a repeated loop into individual subtasks which submit a follow-up task afterwards (if feasible).

This should be considered a hint. Of course TaskExecutor clients are free to ignore this flag and hence the SchedulingTaskExecutor interface overall. However, thread pools will usually indicated a preference for short-lived tasks, to be able to perform more fine-grained scheduling.

Returns
  • true if this TaskExecutor prefers short-lived tasks
