What is thread-local storage, and why is it useful in multithreading? Provide examples of scenarios where thread-local storage can be beneficial.
Thread-local storage (TLS) is a mechanism in multithreading programming that provides each thread in a multi-threaded application with its own separate storage area. This storage is local to the thread and cannot be directly accessed or modified by other threads.
TLS is useful in multithreading for several reasons:
Isolation: TLS allows threads to have their own private data, preventing data conflicts and synchronization overhead between threads. This isolation simplifies concurrent programming.
Efficiency: Accessing thread-local storage is typically faster than accessing shared data, as it avoids contention and synchronization mechanisms required for shared resources.
State Maintenance: Threads can maintain their unique state or context, which is particularly useful in scenarios where threads perform tasks with distinct, non-shared parameters or configurations.
