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.
