What does the "enable optimistic locking" feature do?

The "enable optimistic locking" feature is a mechanism designed to prevent conflicts when multiple users are trying to edit the same record in a system. By allowing records to be edited simultaneously without locking them outright, it promotes a more collaborative environment. However, once a user tries to save their changes, optimistic locking checks if the record has been modified since it was last read.

When this feature is enabled, if two users attempt to make changes to the same record, the first user's save action will succeed. However, if the second user tries to save their changes after the first user's changes have been applied, the system will notify the second user that the record has been modified, ensuring that they are aware of the changes made by the first user. This helps to prevent overwriting data unintentionally and encourages users to review the updates made by others before saving their own changes.

This approach balances the flexibility of simultaneous edits with the need for data integrity, making it a critical feature in collaborative environments where multiple users work on the same set of records.
