yiguolei opened a new issue #1717: RowsetId should be unique globally.
URL: https://github.com/apache/incubator-doris/issues/1717
 
 
   RowsetId is used to identify a batch load file in one replica so that it is unique in one replica[not tablet!!!] currenlty. Same rowsetid does not mean same data for different replica. It has many restrictions, for example:
   
   - BE could not use rowset id as a cache key in file or block cache because rowsetid is not unique among different replicas.
   - BE has to rename rowsetid when clone rowset from other BEs.
   - During offload rowset to object storage like S3/BOS.., the object will be shared among replicas. It must have a unique rowsetid globally.
