For collect_set is it possible to only collect a few elements and then stop? For example
Select user,collect_set(timestamp) from XYZ group by user. For each user, there could be hundreds of timestamps, but I only need 3 or 4 per user. Is there a way to tell collect_set to stop collecting after it's reached a certain number of elements? -- * Robert Li | Integration and Support Engineer | Kontagent Kontagent is Hiring! <http://www.kontagent.com/why/careers/> | Check us out in the press! <http://www.kontagent.com/why/news/>* *Check out our blog: kScope <http://kaleidoscope.kontagent.com/> | Twitter: @Kontagent <http://www.twitter.com/kontagent>*
