What are the differences between shared and exclusive locks?
An example of an AI chatbot conversation about shared vs exclusive locks in database management.
What are the differences between shared and exclusive locks?
Shared locks allow multiple transactions to read a resource simultaneously, while exclusive locks prevent others from accessing it.
Can you give me an example of when to use each type of lock?
Sure! Use a shared lock when multiple users need to read data, and an exclusive lock when a user needs to update data.
What happens if a transaction tries to acquire a lock that is already held?
If a transaction tries to acquire a lock that is already held, it will be blocked until the lock is released.
Are there any performance implications of using these locks?
Yes, using too many exclusive locks can lead to contention and reduced performance, while shared locks can improve read efficiency.
