The Coarse-Grained Lock design pattern is a concurrency control strategy where a single lock is used to protect a large portion of code or multiple related resources. This approach simplifies lock management by reducing the number of locks needed and minimizing the potential for deadlocks. However, it can reduce concurrency as the coarse-grained lock may force threads to wait even when they could safely proceed.
Main Elements of the Pattern:
Single Lock Mechanism: One lock protects a large code segment or multiple resources.
Simplicity: Easier to implement and manage compared to fine-grained locks.
Reduced Concurrency: May lead to lower parallelism as threads may be unnecessarily blocked.
Implementation Steps:
Identify the critical section or related resources that require protection.
Implement a single lock to guard the entire critical section or group of resources.
Ensure that the lock is acquired at the beginning and released at the end of the critical section.
