Optimistic Concurrency Control vs Pessimistic Concurrency Control
Developers should use OCC in high-read, low-conflict environments like web applications or distributed systems where performance is critical and locking overhead is undesirable meets developers should use pessimistic concurrency control in high-conflict environments, such as financial systems or inventory management, where data integrity is critical and concurrent updates could lead to errors. Here's our take.
Optimistic Concurrency Control
Developers should use OCC in high-read, low-conflict environments like web applications or distributed systems where performance is critical and locking overhead is undesirable
Optimistic Concurrency Control
Nice PickDevelopers should use OCC in high-read, low-conflict environments like web applications or distributed systems where performance is critical and locking overhead is undesirable
Pros
- +It's particularly useful for scenarios with infrequent data collisions, such as collaborative editing or e-commerce inventory management, as it reduces blocking and improves throughput compared to pessimistic locking
- +Related to: database-transactions, concurrency-control
Cons
- -Specific tradeoffs depend on your use case
Pessimistic Concurrency Control
Developers should use Pessimistic Concurrency Control in high-conflict environments, such as financial systems or inventory management, where data integrity is critical and concurrent updates could lead to errors
Pros
- +It is ideal for scenarios with long-running transactions or when strict consistency is required, as it prevents race conditions by serializing access to resources
- +Related to: optimistic-concurrency-control, database-transactions
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Optimistic Concurrency Control if: You want it's particularly useful for scenarios with infrequent data collisions, such as collaborative editing or e-commerce inventory management, as it reduces blocking and improves throughput compared to pessimistic locking and can live with specific tradeoffs depend on your use case.
Use Pessimistic Concurrency Control if: You prioritize it is ideal for scenarios with long-running transactions or when strict consistency is required, as it prevents race conditions by serializing access to resources over what Optimistic Concurrency Control offers.
