[GitHub] [incubator-doris] qidaye opened a new issue #6232: [Feature] Fold constant expr by Backend

[GitBox <gi...@apache.org>]

qidaye opened a new issue #6232:
URL: https://github.com/apache/incubator-doris/issues/6232


   Now when Doris is performing some constant expr, if the data query is not involved, it is calculated directly in FE,
   
     eg: `select str_to_date(202009,'%Y%m');` calculate in FE
           `select str_to_date(str,'%Y%m') from tb; `calculate in BE
   
   Now two sets of functions are maintained, and it is easy to cause inconsistent FE/BE calculation results.
   
   Plan to push down the FE calculation to BE. Keep the calculation results consistent to facilitate code maintenance.
