Article Introduction：Thread safe. redis is single threaded. Redis actually adopts the concept of thread closure, closing tasks in one thread, which naturally avoids thread safety issues. However, for compound operations that rely on multiple redis operations, locks are still required, and they may be distributed locks. .

Article Introduction：If thread safety is defined as allowing multiple goroutines to read and write at the same time, then golang's channel is thread safe. There is no need to lock when reading and writing the same channel concurrently.

Article Introduction：1. Overview of thread safety 1.1 What is thread safety issue? First of all, we need to understand that thread scheduling in the operating system is preemptive, or random. This causes the execution order of threads to be uncertain when thread scheduling is executed. The different execution order of some codes does not affect the running results of the program, but there are also some codes that change the execution order and the rewritten running results will be affected, which causes bugs in the program. For code that causes bugs in the program when multi-threaded concurrently Called thread-unsafe code, this is a thread-safety issue. Next, we will introduce a typical example of thread safety problem, the integer self-increment problem. 1.2 A program with thread safety issues. One day, the teacher assigned such a problem: use two threads to transfer variables

Article Introduction：Java provides thread-safe collection classes to solve inconsistency problems caused by multi-threaded concurrent data access, including ConcurrentHashMap (thread-safe hash table), ConcurrentLinkedQueue (thread-safe linked list), CopyOnWriteArrayList (thread-safe list) and ConcurrentSkipListSet (thread-safe skip list) ). These collection classes ensure data consistency and are easy to use by providing atomic operations and good concurrency performance.

Article Introduction：Multi-threaded programming has a unique problem compared to single-threaded programming, which is the issue of thread safety. The so-called thread safety means that if there are multiple threads running at the same time in the process where your code is located, these threads may run this code at the same time. If the results of each run are the same as those of single-threaded runs, and the values ​​of other variables are the same as expected. Thread safety issues are caused by global variables and static variables.
