MVCC improves performance by allowing read operations to occur without waiting for write operations to complete, reducing contention.
What are the drawbacks of using MVCC?
Some drawbacks of MVCC include increased storage requirements for maintaining multiple versions of data and potential complexity in implementation.
In what scenarios is locking preferred over MVCC?
Locking may be preferred in scenarios where strict data consistency is required, such as in financial transactions.
