What are some examples of database locking mechanisms?
Database locking mechanisms are techniques used to control access to data in a database. Examples include row-level locking, table-level locking, and optimistic locking.
Can you explain row-level locking in more detail?
Row-level locking allows multiple transactions to access different rows of the same table simultaneously, reducing contention.
What are the advantages of using optimistic locking?
Optimistic locking assumes that conflicts are rare and allows transactions to proceed without locking resources, improving performance.
Are there any disadvantages to these locking mechanisms?
Yes, while locking mechanisms prevent data inconsistencies, they can lead to deadlocks and reduced concurrency if not managed properly.
