## Proposed changes Issue Number: close #xxx <!--Describe your changes.--> For uniq and agg table, Sometimes use will compute md5 value of some key columns and put md5 as key while put those key as value. For example - when key column is too many, using md5 as key will reduce readed key columns as agg/uniq table will need to read all the key columns although user do not select those key columns - use may need to use array as key, but current doris does not support To improve those cases, I add a table property 'second_key' to let ScanNode to push predicates of those key columns to rowset. -- This is an automated message from the Apache Git Service.
