> @caiconghui @yiguolei It does increase FE's responsibilities, but putting it in FE has its benefits: > > 1. It can control disk balance globally and avoid competing with recovery and cluster balancing. > 2. It reuses the Rebalance mechanism of FE, and there is no need to add a new mechanism for FE. If it is implemented in BE, a set of balance mechanism needs to be repeatedly designed without additional income. I personally think that the scalability of this implementation is not good, especially when there are a large number of machines. If there is data skew in the internal be for each machine, then the repair bottleneck will be thrown to fe. now cluster balancing is to deal with data skew between bes. Then this implementation and cluster balance can run together？how do they collaborate with each other? when the tablet is scheduled to a be, then the be also needs to consider the disk strategy -- This is an automated message from the Apache Git Service.
