morningman opened a new issue #1990: Support creating or adding fixed range partition
URL: https://github.com/apache/incubator-doris/issues/1990
 
 
   **Motivation**
   
   Currently, we only support add partition with range set by `VALUES LESS THAN`,
   This limits that user must specify a series of continuous range of partition. And 
   only specify upper bound of partition range is convenient by not easy to understand.
   
   So we need a more flexible and easy to understand way to describe partition range in 
   CREATE TABLE or ADD PARTITION stmt.
   
   **How to**
   
   We add a new syntax for FIXED RANGE PARTITION:
   
   ```
   PARTITION p1 VALUES [("lower1", "lower2", ...), ("upper1", "upper2", ...)),
   PARTITION p1 VALUES [("lower1", "lower2", ...), ("upper1", "upper2", ...))
   ...
   ```
   
   User can specify both lower and upper bound of a partition range, and range continuity is
   no longer required.
