What does this PR do?
Thread-Specific Storage is a concurrency design pattern where each thread retains its own instance of a shared object, typically achieved using ThreadLocal in Java. By isolating data to each thread, you avoid synchronization overhead and minimize concurrency issues. Common use cases include storing thread-specific contexts, caching stateful objects like DateFormat, or managing per-thread counters without risking data corruption or race conditions.
Key Elements
Isolation of State: Each thread has its own copy of the data, reducing shared mutable state.
ThreadLocal Utility: Java’s ThreadLocal class provides a straightforward way to store data private to each thread.
Initialization & Cleanup: Properly initializing and cleaning up thread-local data is crucial to prevent memory leaks.
Practical Use Cases: Storing per-thread data such as locale-specific formatters, current transaction context, or local caches.
