Re: [jira] [Created] (KYLIN-1467) subquery optimization: remove unused subquery output columns

very interesting observation!

I think it's totally worthwhile to do such optimization because it
contributes to a much quicker user experience in Tableau(or any other BI
tools), as Tableau generates a lot of similar queries. While the patch is
in await status, @chelubai will you please take a second look at your kylin
log to discover more similar bottlenecks, if any?
