Threads And Concurrency Questions Medium
A thread-local variable is a variable that is local to each individual thread in a multi-threaded program. It means that each thread has its own separate copy of the variable, and changes made to the variable by one thread do not affect the value of the variable in other threads. This allows for independent and isolated access to variables by different threads, ensuring thread safety and avoiding potential conflicts or race conditions. Thread-local variables are commonly used in scenarios where multiple threads need to access and modify a shared resource, but each thread requires its own unique instance of that resource.
