### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version doris version: 2.1.7 hive version: 2.3.6 ### What's Wrong? 在Doris中配置连接Hive Catalog对Hive数仓下的表进行单点过滤查询时（表存储格式：parquet）, 发现延迟物化（late materialization）能力失效了。 案例：查询表特别大且查询列中包含大字符串时（如：bbb），会导致FILE_SCAN_OPERATPR操作特别耗时（即使条件列aaa不能过滤出任何数据），且分析发现对所有涉及的列（aaa、bbb）均进行全量扫描读取。比如查询SQL如下： select bbb from test_big_tab where aaa = '111'; ### What You Expected? 想明确为什么通过Hive Catalog进行单点过滤查询时延迟物化能力未生效？是否是配置错误还是版本不支持导致，亦或是存在的问题？ ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
