first check the cache, when there are no concurrent requests, the database will be searched. However, in an extreme case, when a large number of requests are concurrently sent, the cache of the judgment logic check will not be found at the same time, that is, if the database data has not been cached, The concurrency will be searched by the database, and the database still has the risk of concurrent calls.

The core of the visitor pattern is to solve the problem of double distribution of a. Foo (B. A simple example is provided. Good guys beat a bitch. Good guys include South boxing and north leg, and bad guys include devils, sticks, and b2.

This way, if only one thread, then we have to change the ball in the creation of a small ball, if the number of smaller balls is not a problem, but when the number of balls, every convenience will be used for a period of time, then there will certainly be a delay, so we need to divide this place into two threads,
