Date Thu, 16 Mar 2017 03:51:27 GMT
Github user QiangCai commented on the issue:
    1. If user has not mentioned any sort column then it will go to old flow, sorting based
on all dimension column
    2. yes
    3. During dataloading, the start/end key of blocklet info contain only sort columns.
    4. For dataloading, just use sort columns to build start/end key of blocklet info. 
    Code line: 1041
        For select query, juse use sort columns to bulid start/end key of filters. 
    Code line: 1159 and 1206
    I have remove date & timestamp datatype from no-dcitonary.
    Better to raise another pr to implement new numeric datatype encoding.
