   # [DRILL-7578](https://issues.apache.org/jira/browse/DRILL-7578): HDF5 
Metadata Queries Fail with Large Files
   
   ## Description
   HDF5 metadata queries were failing for files with large datasets.  This PR 
adds a configuration option to avoid projecting the entire dataset in metadata 
queries and hence solves this issue.
   
   ## Documentation
   Added this to the HDF5 documentation:
   
   * `projectDatasetInMetadataQuery`:  This causes the plugin to project the 
data set in metadata queries.  Should be `false` for large files.
   
   ## Testing
   Added new unit test to cover this configuration.
