What is pessimistic locking in databases?
An example of an AI chatbot conversation about pessimistic locking in databases.
What is pessimistic locking in databases?
Pessimistic locking is a concurrency control mechanism that prevents multiple transactions from modifying the same data simultaneously.
How does it differ from optimistic locking?
Unlike optimistic locking, which allows transactions to proceed without locking until commit time, pessimistic locking locks the data right away.
What are the advantages of using pessimistic locking?
The main advantages include preventing lost updates and ensuring data integrity in high-contention environments.
Are there any downsides to using pessimistic locking?
Yes, it can lead to reduced concurrency and potential deadlocks, as transactions may wait for each other to release locks.
In what scenarios is pessimistic locking recommended?
It's recommended in scenarios with high contention for resources, such as banking systems or inventory management.
