Hi Dong, some thoughts on your second mail. Since currently logs for multiple partitions are created sequentially not in parallel, it's probably okay for us to simply select the directory with most disk spaces in a single round of `nextLogDir` calling. which can be guaranteed to lead to extreme skew. Does it make any senses?

Will take some time to figure out an algorithm to better handle the situation you mentioned. Thanks again. ________________________________ 发件人: Dong Lin <lindon...@gmail.com> 发送时间: 2017年8月3日 12:07 收件人: dev@kafka.apache.org 主题: Re: 答复: [DISCUSS] KIP-178: Size-based log directory selection strategy Hu, I think this is worth discussion even if it doesn't require new config. Could you also read my second email?
