I'm working on an auction app. In an Auction object I store the current_high_bid for that auction.
When a new_bid comes in, I: 1) retrieve the current_high_bid field of the Auction object 2) compare it with the new_bid 3) if the new bid is higher than current_high_bid, I update current_high_bid to the value of the new_bid. but there's a (slight) chance that between steps (1) and (3) a different user could've submitted an even higher bid which then become the current_high_bid. In that case step 3 should not proceed. What can I do to make sure such a situation does not arise?
