public class PrioritizedEsThreadPoolExecutor extends EsThreadPoolExecutor
A prioritizing executor which uses a priority queue as a work queue. The jobs that will be submitted will be treated asPrioritizedRunnable
and/orPrioritizedCallable
, those tasks that are not instances of these two will be wrapped and assign a defaultPriority.NORMAL
priority.Note, if two tasks have the same priority, the first to arrive will be executed first (FIFO style).
