Response sample:

> Just like a normal cube need a "partition start date" on creation (which will be used as the start point of the first segment), a streaming cube also need a starting point of the topic; but it will be a collection of offsets (for all partitions). Otherwise Kylin has to build from the topic's very begining, which may not be expected.
