thread storage containers

Develop a data storage container using internal classes to store data containers Case study: a container is developed to store key-value pairs, English names, Chinese names, and internal classes; Case Design: ① Use static internal classes to encapsulate key-value pairs; ② By default, the container size is 5, which is twice the size of the container if the container size exceeds 5; ③ Call the entryArrays met

Usage scenarios:1. When copying files, it is common for a thread to call an interface to copy files, which requires caching the data, and if each file needs to create a separate cache, the memory fragmentation is large.If you create a static memory area, when multithreading calls the same interface, multiple threads using the same static cache can cause data pollution. The best way is that the cache is visible only to this

Scene:1. You need to count the number of objects created on a thread.2. When the heap space is created, it needs to be destroyed based on the thread needs to be created and ended.3. Because the scope is that a thread can only see its own stored data, it does not require a critical section or mutex to maintain its own heap memory. Join if implemented with global S

There is also an important concept in multi-threaded programming: Thread Local store (TLS, Thread Local Storage). In boost, TLS is also called TSS, thread specific storage.Boost::The thread Library provides us with a simple TLS object-oriented encapsulation interface. The fo

[Concurrent parallel] _ [C/C ++] _ [use a Thread to locally store Thread Local Storage (TLS) to call the copy file interface] Use Cases: 1. When copying a file, a thread generally calls an interface to copy the file. At this time, data needs to be cached. If each file needs to create an independent cache, the memory f

The main work of the InnoDB Storage engine is completed in a separate background thread master thread.The main thread of the master thread mainly includes the following cycles:Main loopBackground loopRefresh loop flush loopPause loop suspend loop Void master_thread (){Loop:For (int I = 0; I {Sleep 1 second if necessary

Citation Source: Https://www.cse.wustl.edu/~schmidt/PDF/TSS-pattern.pdfSummary:Multithreading can theoretically improve program performance, but in reality, multithreading is often worse than a single thread because of the overhead of acquiring and releasing locks. In addition, multithreaded programming is difficult to avoid competition and deadlocks that require complex concurrency control protocols.This article introduces
