Class FixedThreadPoolBulkhead

java.lang.Object

io.github.resilience4j.bulkhead.internal.FixedThreadPoolBulkhead

All Implemented Interfaces:

ThreadPoolBulkhead

public class FixedThreadPoolBulkhead
extends java.lang.Object
implements ThreadPoolBulkhead

A Bulkhead implementation based on a fixed ThreadPoolExecutor. which is based into the thread pool execution handling : 1- submit service call through bulk head thread pool 2- if there is free thread from the thread pool or the queue is not yet full , it will be permitted 3- otherwise the thread pool will throw RejectedExecutionException which mean is not permitted
