How can I implement MVCC in SQL?
To implement MVCC (Multi-Version Concurrency Control) in SQL, you can use techniques like versioning rows or using timestamps.
What are the benefits of using MVCC?
MVCC allows for higher concurrency, reduces locking, and improves performance in multi-user environments.
Can you give me an example of MVCC in action?
Sure! In PostgreSQL, when a transaction updates a row, it creates a new version of that row while keeping the old version for other transactions.
Are there any drawbacks to using MVCC?
Yes, MVCC can increase storage requirements due to multiple versions of data and may complicate garbage collection.
