kangpinghuang opened a new issue #2210: support online upgrade from alpha rowset to beta rowset
URL: https://github.com/apache/incubator-doris/issues/2210
 
 
   In next release, BetaRowset will be introduced to users, which brings many features. Related issue #1305.
   
   We should support online upgrade, and we will face the following problems:
   1. what if error happens, is there any method to rollback data to reduce the lose.
   2. how old bins support new format segment, because there is clone task
   
   For problem 1, I develop a segment tool to convert BetaRowset to AlphaRowset
   For problem 2, here is my solution: to convert BetaRowset to AlphaRowset when clone from new bin.
