Prevent overwriting of identical resources being edited simultaneously

Hello everyone, I am considering realising my next project with Ash. I am currently getting an overview of the available options and have already read Rebecca and Zach’s book. I am currently wondering whether there is a mechanism in Ash that prevents a resource being edited simultaneously from simply being overwritten.

Note: ‘etag header mid-air collisions’.

I’m not sure if this is exactly what you’re looking for, but there is support for optimistic locks.

Thank you, that’s exactly what I’m looking for. The ‘Introduction’ section on the website explains exactly what I mean.

“Often, when working with resources, we want to ensure that a record has not been edited since we last read it. We may want this for UX reasons, or for ensuring data consistency, etc.”
