What are the different database locking techniques?
An example of an AI chatbot conversation about database locking techniques and their importance in concurrency control.
What are the different database locking techniques?
There are several database locking techniques, including pessimistic locking, optimistic locking, and row-level locking. Would you like to know more about any specific technique?
Can you explain pessimistic locking?
Pessimistic locking involves locking a resource as soon as it is acquired, preventing other transactions from accessing it until the lock is released. This is useful in high-contention scenarios.
What about optimistic locking?
Optimistic locking allows multiple transactions to proceed without locking resources initially. It checks for conflicts before committing, which can improve performance in low-contention scenarios.
When should I use row-level locking?
Row-level locking is ideal when you need to allow concurrent access to different rows in a table, minimizing contention and improving throughput.
