What are the differences between optimistic and pessimistic locking?
An example of an AI chatbot conversation about optimistic vs pessimistic locking in database management.
Can you explain the differences between optimistic and pessimistic locking?
Sure! Optimistic locking assumes that multiple transactions can complete without affecting each other, while pessimistic locking assumes conflicts will occur and locks resources to prevent them.
What are the advantages of using optimistic locking?
Optimistic locking is generally more efficient in environments with low contention, as it allows transactions to proceed without locking resources until they are ready to commit.
Are there any downsides to optimistic locking?
Yes, if conflicts do occur, transactions may need to be rolled back, which can lead to increased overhead and complexity in handling retries.
When should I use pessimistic locking instead?
Pessimistic locking is preferable in high contention scenarios where the likelihood of conflicts is high, ensuring data integrity by locking resources.
