describe: report about compression method
m-mohr opened this issue · comments
I think it would be interesting (e.g. for investigating #46) to report the compression method in gpq describe
I added output about the compression to the describe output. This is a simplified view of the actual compression. In a Parquet file, compression can vary per column and per row group. The describe output only summarizes the compression levels in the first row group. For nested fields, the --format json output includes the compression for all fields. The non-JSON output only describes the top level logical fields.
