Optimistic Concurrency vs Pessimistic Concurrency
Developers should use optimistic concurrency in high-read, low-write scenarios where conflicts are infrequent, such as web applications with many concurrent users reading data meets developers should use pessimistic concurrency in scenarios where data integrity is critical and conflicts are frequent, such as financial systems, inventory management, or booking applications where concurrent updates could lead to inconsistencies. Here's our take.
Optimistic Concurrency
Developers should use optimistic concurrency in high-read, low-write scenarios where conflicts are infrequent, such as web applications with many concurrent users reading data
Optimistic Concurrency
Nice PickDevelopers should use optimistic concurrency in high-read, low-write scenarios where conflicts are infrequent, such as web applications with many concurrent users reading data
Pros
- +It improves performance by avoiding locks, reducing contention, and increasing throughput, making it ideal for scalable systems like e-commerce platforms or social media feeds
- +Related to: database-transactions, distributed-systems
Cons
- -Specific tradeoffs depend on your use case
Pessimistic Concurrency
Developers should use pessimistic concurrency in scenarios where data integrity is critical and conflicts are frequent, such as financial systems, inventory management, or booking applications where concurrent updates could lead to inconsistencies
Pros
- +It's ideal when transactions are long-running or when the cost of rolling back a transaction due to a conflict is high, as it prevents conflicts proactively rather than detecting them after they occur
- +Related to: database-transactions, optimistic-concurrency
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Optimistic Concurrency if: You want it improves performance by avoiding locks, reducing contention, and increasing throughput, making it ideal for scalable systems like e-commerce platforms or social media feeds and can live with specific tradeoffs depend on your use case.
Use Pessimistic Concurrency if: You prioritize it's ideal when transactions are long-running or when the cost of rolling back a transaction due to a conflict is high, as it prevents conflicts proactively rather than detecting them after they occur over what Optimistic Concurrency offers.
Developers should use optimistic concurrency in high-read, low-write scenarios where conflicts are infrequent, such as web applications with many concurrent users reading data
