vert.x - 限制事件循环的数量

Question

在 vertx docs他们提到有可能限制每个 vertx 实例的事件循环线程数:

Instead of a single event loop, each Vertx instance maintains several event loops. By default we choose the number based on the number of available cores on the machine, but this can be overridden.

也许有人知道该怎么做？ (我需要它用于调试目的)

Answer 1

Vertx vertx = Vertx.vertx(new VertxOptions().setEventLoopPoolSize(1));

默认情况下是:

public static final int DEFAULT_EVENT_LOOP_POOL_SIZE = 2 * Runtime.getRuntime().availableProcessors();
