I think the scenario mentioned by @errose28 is a case when the object is not overwritten, which I think is not a major problem. However, a problem is if the object is overwritten (with different object ID) and there were some pending transactions that was acting on the previous overwritten object. I think this is unlikely since it requires openKey and commitKey almost instantaneously, but it is possible. > However, I was thinking that we could potentially adopt this logic for conditional requests, primarily for two reasons: Yes, I think @peterxcli has propose similar logic as well. For now I think we can use this for conditional requests. -- This is an automated message from the Apache Git Service.
