## Proposed changes ### Issue Query results should not have empty values. ``` use regresssion.multi_catalog; select commit_id from github_events_orc WHERE (event_type = 'CommitCommentEvent') AND commit_id != "" limit 10; ``` ``` +------------------------------------------+ | commit_id | +------------------------------------------+ | 685c1fd8dbbdc10c042932f9a9f88be00ff96c75 | | 685c1fd8dbbdc10c042932f9a9f88be00ff96c75 | | 4e3ab2ff2d2474f5d51334b9b0fdf17e9845a166 | | | | | | | | | | | | | | 7191c20cb49da07a7fc16aa32dc0de4faff528b2 | +------------------------------------------+ 10 rows in set (0.54 sec) ``` ### Resolution - Fix orc dict filter null value issue in `_convert_dict_cols_to_string_cols` which caused incorrect result. - Rollback to use `insert_many_strings_overflow` for performance. ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
