Proposed changes
A row of complex type may be stored across two(or more) pages, and the parameter
align_rowsindicates that whether the reader should read the remaining value of the last row in previous page.Further comments
If this is a relatively large or complex change, kick off the discussion at dev@doris.apache.org by explaining why you chose the solution you did and what alternatives you considered, etc...
