This is a video I cam across that's from Berlin Buzzwords Querying 24 Billion Records in 900ms. The presentation is only 20 minutes long, but includes slides which is very helpful.
The speaker gives a lot of good information about trying to scale out ES on AWS to handle 24B records. They were able to do it successfully, which is excellent. They ended up moving to dedicated hardware to reduce the AWS cost.
