Hello, I am researching methods to achieve high throughput for a learning chat application I am designing as a self-led student. I came across the Multiversion Control method of ACID and have a theoretical question: though it seems remote that a reader of data wouldn't get an "old" read what has been the experience and when this occurs what methods are available to alert the read user that data has been updated?
Thank you, Joey [Non-text portions of this message have been removed]
