With the completion of Q1-Q2 / 2018, clickhouse support store data at multiple disk volumes of a single server at the level of DBs or tables. Is there a plan to support this feature at the partitions?

We want migrate PB-level data to clickhouse hope the partitions can be stored on different performance medias likes hdd, ssd .

We define hot/cold data based on partitions by date, we hope the cold data partitions can be storage on HDD , and hot data partitions can be storage on SSD, In order to achieve good economic benefits.

I think this is a common practice in the field of big data. How do you think about it?
