# [DRILL-7991](https://issues.apache.org/jira/browse/DRILL-7991): Add
Configuration Option to HDF5 Reader to Skip Preview
## Description
When viewing HDF5 metadata, Drill will render a preview of underlying
datasets. For large files or very nested datasets, or large files, this can
cause serious performance degradations and isn't necessarily very useful.
This PR adds a configuration option to the configuration for HDF5 which
allows you to disable the preview in the metadata view.
## Documentation
Updated README for the HDF5 reader.
## Testing
Added additional unit test.
