我有一个Laravel应用程序，它接收来自Webhook的响应。数据是来自支付网关的交易信息。在一天中的某些时候，我可以在几秒钟内收到数百个回复。
我将所有响应放入队列，然后进行处理。 Laravel让我可以选择指定可以同时处理给定队列的最大工人数。我将此设置为10，但是出现很多死锁错误。
我要做的就是将数据插入表中。我唯一的主键/唯一键是“ id”，它随每次插入而自动递增。
我不明白为什么会发生这些死锁，因为这是一个简单的插入，其中表只有1个唯一键。
Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction
