Test Dataset: viewer-test-50-small-images-ok

Purpose: Demonstrate dataset viewer behavior with large images and row group sizing.

Dataset Details

• Number of images: 50
• Total size: ~167MB
• Average per image: ~3.3MB

Expected Behavior

50 smaller images (~3.5MB each, ~175MB total). Well under the 300MB limit.

Prediction: SHOULD WORK - Under 300MB limit

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. See: https://github.com/huggingface/dataset-viewer for context.
