gaogao created KYLIN-5215: ----------------------------- Summary: The metadata information returned by Kylin pushdown query and Cube query is inconsistent Key: KYLIN-5215 URL: https://issues.apache.org/jira/browse/KYLIN-5215 Project: Kylin Issue Type: Bug Components: Spark Engine Affects Versions: v4.0.1, all Environment: kylin 4.0.1 Reporter: gaogao Attachments: cube_query.png, pushdown_query.png
问题: 在下压查询中返回的结果 和 cube 查询的结果不一致,下压查询中 columnMetas 的 label 和 name 字段会默认转换成大写! 对应源码类 PushDownRunnerSparkImpl 50行 : {code:java} // fill in selected column meta for (int i = 0; i < columnCount; ++i) { int nullable = fieldList.get(i).isNullable() ? 1 : 0; columnMetas.add(new SelectedColumnMeta(false, false, false, false, nullable, true, Integer.MAX_VALUE, fieldList.get(i).getName().toUpperCase(Locale.ROOT), fieldList.get(i).getName().toUpperCase(Locale.ROOT), null, null, null, fieldList.get(i).getPrecision(), fieldList.get(i).getScale(), fieldList.get(i).getDataType(), fieldList.get(i).getDataTypeName(), false, false, false)); } {code} pushdown query: !c:\Users\Administrator\AppData\Local\YNote\data\weixinobU7VjlOcNgcm0ZbmNGYzYRPZ__4\401fe7a7ea05495799145f2d413b0da4\clipboard.png! cube query: !c:\Users\Administrator\AppData\Local\YNote\data\weixinobU7VjlOcNgcm0ZbmNGYzYRPZ__4\0ef826f0229f42b59c4ad946a08bf6f3\clipboard.png! 我认为这个问题应该修复,因为在尝试对接superset时发现,有些此类框架会强校验元数据列的大小写,如果默认进行转换会导致无法适配,且cube query和pushdown query查询的元数据列结果不一致这也是无法接受的。 如果讨论有需要的话,我可以修复他,谢谢~ -- This message was sent by Atlassian Jira (v8.20.10#820010)
