TaskExecutor
extension exposing
scheduling characteristics that are relevant to potential task submitters.
Scheduling clients are encouraged to submit
Runnables
that match the exposed preferences
of the TaskExecutor
implementation in use.
Note: SchedulingTaskExecutor
implementations are encouraged to also
implement the AsyncListenableTaskExecutor
interface. This is not required due to the dependency on Spring 4.0's
ListenableFuture
interface,
which would make it impossible for third-party executor implementations
to remain compatible with both Spring 4.0 and Spring 3.x.

default boolean prefersShortLivedTasks()Does thisTaskExecutor
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 theSchedulingTaskExecutor
interface overall. However, thread pools will usually indicated a preference for short-lived tasks, allowing for more fine-grained scheduling.- Returns:
true
if this executor prefers short-lived tasks (the default),false
otherwise (for treatment like a regularTaskExecutor
)
