      Description

      COMPRESSION_CODEC is supported as a query option.

      It probably makes sense to provide a finer granularity control on the scope of compression such as table and/or even columns.

      There could also be scenarios where a select few columns (such as variable length strings) could be compressed while others (such as integer family columns) remain uncompressed for performance. Parquet's unit of compression is a page and so it makes sense to provide capability to compress a given column.
