  • Event- The Event module provides an event object for collaborative shared data operations. It allows synchronized operations between multiple fibers (coroutines) to achieve cooperative multitasking. The event object has three methods: wait, pulse and clear. The wait method will block the current fiber until the event is triggered, the pulse method will wake up all fibers waiting for the event, and the clear method will reset the event flag to false. By using the coroutine.Event module, developers can control the execution sequence and data sharing between fibers to implement complex business logic.

It is implemented based on Google's open source LevelDB and has the advantages of efficiency, reliability, and scalability.
  • Lock- Lock is a built-in object that can be used to control concurrent access to fibers. You can acquire a lock through one fiber to prevent other fibers from acquiring it at the same time. Lock can be created through coroutine.Lock() function
  • LruCache- LruCache (Least Recently Used Cache) is a class used to maintain LRU cache. It can store a certain number of values ​​and maintain the size of the container. When new data comes in, if the container has not reached the size limit, the new data can be added directly to the container. If the container is full, the container will evict the least recently used data
