## B.11 `parqlook`: Presents information about a parquet file

`parqlook` is a utility to display information about parquet files. It can display the parquet schema, the file-level key-value metadata items, information about the organisation of row and column storage within the file, and the content of a VOTable file associated with the data according to the VOParquet convention. By default all of this information is displayed, but the `items` parameter can be used to define exactly what gets output.

Other parquet file inspection utilities exist and may do a better job, but this tool may be convenient if you have STILTS installed. Note it does not provide facilities for examining the actual data content in a parquet file, but generic STILTS table commands such as `tpipe` can be used to do that.

Note: this command will only work if the parquet support libraries are on the classpath at runtime; depending on how you are running STILTS this may not be the case. See the note at Section 5.1.1.11.

Note: This command is currently experimental and its behaviour may change in future releases.
