[−][src]Struct datafusion::physical_plan::parquet::ParquetPartition
Represents one partition of a Parquet data set and this currently means one Parquet file.
In the future it would be good to support subsets of files based on ranges of row groups so that we can better parallelize reads of large files across available cores (see ARROW-10995).
We may also want to support reading Parquet files that are partitioned based on a key and in this case we would want this partition struct to represent multiple files for a given partition key (see ARROW-11019).
