How do I implement optimistic concurrency in my application?

Optimistic concurrency control allows multiple transactions to occur without locking resources. You can implement it by using versioning.

What is versioning in this context?

Versioning involves adding a version number to your data records. Each time a record is updated, the version number increments.

What happens if two users try to update the same record simultaneously?

If two users attempt to update the same record, the system checks the version number. If it has changed since the user retrieved it, an error occurs.

How can I handle the error when a version conflict happens?

You can handle it by notifying the user, allowing them to refresh the data, and then reapply their changes.
