> Bad/Big queries are a huge threat to the overall performance and stability of
> Kylin. We occasionally saw some of these queries either causing heavy GC
> activities or crashing regionservers. I'd like to start a series of work to
> make Kylin more resilient to bad queries.
> This is an umbrella jira to relating works.
