aglinxinyuan opened a new issue, #4363: URL: https://github.com/apache/texera/issues/4363
### Feature Summary Add a new Dataset Selector operator that allows users to select a dataset version and output one tuple per file in that version. The output should use Texera’s existing dataset file path format, for example: ``` /ownerEmail/dataset1/v1/file1.csv /ownerEmail/dataset1/v1/file2.csv /ownerEmail/dataset1/v1/file3.csv ``` This would make it easier to connect dataset-managed files to downstream file-based operators without manually selecting files one by one. ### Proposed Solution or Design Introduce a new source operator named Dataset Selector. - In the property panel, users select a dataset and a dataset version. - The operator enumerates all files in the selected dataset version. - The operator outputs one tuple per file path using Texera’s dataset path format. - The operator should remain invalid until a dataset version is selected. - The output should be directly consumable by downstream operators that accept file path strings. ### Impact / Priority (P2)Medium – useful enhancement ### Affected Area _No response_ -- This is an automated message from the Apache Git Service.
