It's good to see a Redshift evaluation. I'm wondering how does Redshift compare to hadoop airbnb setup when taking data loading and transformation into consideration as well as running aggregate queries? I mean if you want to run analysis fairly often, do you need to reload everything in Redshift? From maintenance point of view, is Hadoop setup more flexible and cheaper than Redshift?

The hadoop setup we have is actually EMR, and we use s3 for data storage, so for us Hive/Hadoop doesn't save much in terms of data loading. And once you have a process setup to load and update the data in Redshift, you don't have to reload everything
