🔍 What is Distributed Locking?
In traditional single-machine applications, a lock is a way to control access to a resource, like a file, variable, or database entry, ensuring that only one process or thread can interact with it at any given time. Distributed locking extends this concept to distributed systems where resources are accessed by multiple, independent nodes that don’t share a common memory space or a single OS lock manager.
It is a synchronization mechanism designed to control access to shared resources in a distributed system, where multiple processes or nodes may attempt to access and modify the same resource concurrently. A distributed lock ensures exclusive access to a shared resource across multiple nodes in a distributed system. It allows only one client to access or modify a resource at any given time, preventing issues such as data corruption, inconsistency, or race conditions.
🧩 Why Use Distributed Locking?
Distributed locking is used to solve several critical challenges in distributed systems, including:
- Ensuring Consistency and Avoiding Conflicts: Distributed locks help prevent race conditions where two…
