What is the performance impact of using shared locks in databases?
Shared locks allow multiple transactions to read data simultaneously, but they can lead to contention if many transactions try to acquire them.
How do shared locks compare to exclusive locks in terms of performance?
Exclusive locks prevent other transactions from accessing the locked data, which can lead to higher contention and lower throughput compared to shared locks.
Are there scenarios where shared locks can degrade performance?
Yes, if there are many concurrent transactions trying to acquire shared locks on the same resource, it can lead to bottlenecks.
What strategies can be used to optimize performance with shared locks?
Optimizing query performance, reducing lock contention, and using lock timeouts can help improve performance with shared locks.
