> Currently kylin allows users to specify some time ranges like (7days, 30days, 
> 365days) to instruct auto merging daily segments. However, the design fails 
> to respect the boundary of calendar week/month/year, which is often useful 
> for real applications. For example, if a query only wants a month's data by 
> providing a filter like `date > 2010-01-01 and data < 2010-02-01`, with 
> current auto merging design we may end up with visiting two adjacent 30 days 
> long segments.
