我觉得 101行 还是有问题 应该加锁 做重试
我这边是用golang写的:
s.lock2.Lock()
if atomic.LoadInt64(&s.currentId) == s.segments[s.segIndex()].MaxId {
s.lock2.Unlock()
goto retry
}
id := atomic.AddInt64(&s.currentId, 1)
log.Info("getID from sucess : %d", id-1)
s.lock2.Unlock()
你好 请问心跳有什么作用?没看懂
这里 如果是异步的话 不会有问题么?
thresholdHandler() 不会被多次调用?
这里起始cid=0 step=10000,如果同时10001个 请求全部同时过来 ,并且10001通过83行的判断(这里是第一重,没有加锁,这里的cid都是0)然后在原子自增处阻塞 就会超过步长啊,
你好,我有个疑问,这个uid生成器有解决不同的机器时间不同步的问题吗?
例如,第一次请求的机器比第二次请求的机器时钟快,那么id不就不自增了吗?
spring boot starter,现在分布式都是需要支持这个的了,好可惜呀!
