What is optimistic concurrency?
An example of an AI chatbot conversation about optimistic concurrency control in databases.
Can you explain what optimistic concurrency is?
Optimistic concurrency is a database management approach that assumes multiple transactions can complete without affecting each other.
How does it differ from pessimistic concurrency?
Unlike pessimistic concurrency, which locks resources to prevent conflicts, optimistic concurrency allows transactions to proceed without locking, checking for conflicts only at commit time.
What are the advantages of using optimistic concurrency?
The main advantages include improved performance and reduced contention, as it allows more transactions to proceed simultaneously.
Are there any downsides to optimistic concurrency?
Yes, if conflicts occur frequently, it can lead to increased transaction rollbacks and retries, which may affect performance.
