It's better not shut the door completely. > @adoroszlai , I'm not sure if it's feasible that we provide a option of calculating the bytesInUsed for each bucket during 1.0.0 -> 1.1. upgrade to user? So that user has the choice either tolerate the inaccurate bytesInUsed or a relative longer upgrade time to get accurate bytesInUsed of buckets. Hi @ChenSammi, I think it's dangerous recalculating usedBytes in upgrade . If the amount of data is too large, it will greatly increase the time, and if the processing is not good, it will cause the upgrade to fail. If we want use Quota in old buckets, we can add a command to recalculate bucket usedBytes to minimize the impact. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
