What is the difference between shared locks and read locks?
An example of an AI chatbot conversation about shared locks and read locks in database management.
What is the difference between shared locks and read locks?
Shared locks and read locks are often used interchangeably. Both allow multiple transactions to read a resource without modifying it.
Can you explain how they work in a database?
Sure! A shared lock permits multiple transactions to read a resource, but no transaction can modify it until all shared locks are released.
What happens if a write lock is requested while there are shared locks?
If a write lock is requested, it will be blocked until all shared locks are released, ensuring data integrity.
Are there any performance implications of using shared locks?
Yes, while shared locks allow concurrent reads, they can lead to contention if many transactions are trying to acquire write locks.
