Internet applications often need to cope with large concurrency, and in order to improve QPS, the central cache (such as memcache) and local caching are typically used. The request passes through the local cache first, and if it does not, the request penetrates into the central cache and, if not, queries the database directly and flushes the queried data to the central

Grand Central Dispatch (GCD) is a powerful way to perform multithreaded tasks, whether you are asynchronous or synchronous at the time of the callback, and you can optimize the application to support multi-core processors and other symmetric multi-processing systems. In the process of development, only the tasks to be executed and added to the appropriate dispatch queue, GCD can generate the necessary threads and plan to perform the task. The Dispatch

Introduced:The Grand Central Dispatch abbreviation (GCD) is the technology developed by Apple to optimize applications that support multi-core processors and other symmetric multi-processing systems. This is based on the thread pool pattern that the task executes in parallel.
