解説

When set to true, the provider will aggregate all the files in URI directory into a single result. With this option enabled, the AggregatedFiles will be exposed which can be used to query the dataset. By default the first file in the folder is used to define the schema, however MetadataDiscoveryURI can be specified to use a different file instead.
