What is the difference between optimistic and pessimistic concurrency control?
An example of an AI chatbot conversation about optimistic vs pessimistic concurrency control in databases.
What is the difference between optimistic and pessimistic concurrency control?
Optimistic concurrency control assumes that conflicts are rare and allows transactions to proceed without locking resources. It checks for conflicts before committing.
Can you give me an example of when to use optimistic concurrency?
Sure! Optimistic concurrency is ideal for applications with many read operations and few write operations, like a social media platform.
What about pessimistic concurrency? When should I use that?
Pessimistic concurrency is best for scenarios where conflicts are likely, such as banking systems, where transactions must be tightly controlled.
Are there any downsides to using optimistic concurrency?
Yes, if conflicts do occur frequently, it can lead to increased transaction rollbacks and reduced performance.
