| # Test Dataset: viewer-test-large-images-fail | |
| **Purpose**: Demonstrate dataset viewer behavior with large images and row group sizing. | |
| ## Dataset Details | |
| - **Number of images**: 50 | |
| - **Total size**: ~632MB | |
| - **Average per image**: ~12.6MB | |
| ## Expected Behavior | |
| 50 large images (~14MB each, ~700MB total). With 100-row row groups, all images land in one ~700MB row group, exceeding the 300MB scan limit. | |
| **Prediction**: FAIL - Scan size limit exceeded | |
| ## Technical Context | |
| The dataset viewer converts imagefolder datasets to parquet with: | |
| - Row group size: 100 rows (for image datasets) | |
| - Scan size limit: 300MB | |
| If all images end up in one row group and exceed 300MB, the viewer fails with: | |
| ``` | |
| Scan size limit exceeded: attempted to read X bytes, limit is 300000000 bytes | |
| ``` | |
| ## Related Issue | |
| This dataset was created to help debug row group sizing for large images. | |
