本站中文解释
MySQL参数`max_insert_delayed_threads`用于设置MySQL服务器可以同时处理延时插入（INSERT DELAYED）查询的线程数量。
该参数默认值为20，最大值由hyper-threading和服务器上的CPU数量决定。如果客户端对MySQL Server发出的INSERT DELAYED查询过多，而max_insert_delayed_threads参数值太低，则MySQL服务器可能无法处理这些查询，从而导致客户端长时间处于等待状态。
要设置该参数，可以在MySQL数据库实例中执行以下查询:
“`sql
SET GLOBAL max_insert_delayed_threads=n;
“`
其中`n`为需要设置的参数值。
