Hi, I tried to gain more clarity on UPDATE queries but documentation on it is a bit limited and I can't find an answer to the following question.
How can I confidently identify a triple to mutate it? As far as I'm aware the complete triple (subject_id + property + value) is the identifier itself, there are no other ids that can uniquely identify it, right?
So for example, if I have a blog post and I want to edit its title in my CMS I need to target it with something like:
:post_123 :title "Current blog title"
If that's the only way to target it, by holding on to the value, what's the approach to concurrent edits? Imagine two users are editing the same blog post and have it open in their interface. One of them changes the title and shortly after the other one wants to make an edit as well. In a regular db world that would not be a problem, subsequent edits would override the previous ones. But here once one of them changes the title the other one won't be able to target it without first obtaining the updated value, right? Is that really the case? Are there any strategies to concurrent edits like the above?
I'd appreciate any help, thank you!
