An example of an AI chatbot conversation about database concurrency control techniques.
What are some examples of database concurrency control techniques?
There are several techniques for concurrency control in databases, such as locking, timestamp ordering, and optimistic concurrency control.
Can you explain how locking works?
Locking prevents multiple transactions from accessing the same data simultaneously. It can be either exclusive or shared.
What is optimistic concurrency control?
Optimistic concurrency control allows transactions to proceed without locking resources, checking for conflicts only at commit time.
Are there any drawbacks to these techniques?
Yes, locking can lead to deadlocks, while optimistic control may result in higher rollback rates if conflicts are frequent.
