BTW if you do add a config setting, a better name would be
`spark.sql.hints.parquetFilterPushdown`; our other setting names don't start
with `org.apache`. An even better option though might be to put it in the SQL
statement itself, so users can do it on a per-query basis, though that probably
requires nasty changes to the parser. But I'd still prefer to either always
turn this on (if the penalty isn't huge) or leave it off for now and not
introduce a new setting.
