How does locking work in databases?
An example of an AI chatbot conversation about database locking mechanisms.
Can you explain how locking works in databases?
Sure! Locking in databases is a mechanism to control access to data, ensuring that multiple transactions do not interfere with each other.
What are the different types of locks?
There are mainly two types of locks: shared locks, which allow multiple transactions to read data, and exclusive locks, which prevent others from accessing the data until the lock is released.
How does locking prevent deadlocks?
Locking can help prevent deadlocks by using timeout mechanisms or lock ordering, ensuring that transactions do not wait indefinitely for each other.
What happens if a transaction holds a lock for too long?
If a transaction holds a lock for too long, it can lead to performance issues, as other transactions may be blocked, causing delays.
