What are some examples of locking mechanisms in databases?
Locking mechanisms in databases include row-level locks, table-level locks, 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 about table-level locking? How does it work?
Table-level locking locks the entire table for a transaction, preventing other transactions from accessing any rows until it's released.
Are there any downsides to using table-level locks?
Yes, table-level locks can lead to increased contention and reduced concurrency, which may slow down performance.
