What are the different database concurrency control techniques?
There are several techniques for concurrency control in databases, including locking, timestamp ordering, and optimistic concurrency control.
Can you explain how locking works in concurrency control?
Locking involves restricting access to data by multiple transactions. It can be either exclusive or shared, depending on the operation.
What are the advantages of using optimistic concurrency control?
Optimistic concurrency control allows transactions to proceed without locking resources, reducing wait times and improving performance.
Are there any disadvantages to optimistic concurrency control?
Yes, if conflicts occur frequently, it can lead to increased rollbacks and wasted resources, making it less efficient.
