Prior to using the Airpal/PrestoDB combo, Airbnb used Amazon Web Service's Redshift service.
Redshift requires a set of ETL (Extract, transform and load) tools to prepare the data. It had a limit on how many queries can be run at once, which could limit wider use of the data. Also, Airbnb developers found the Redshift error messages to be obtuse, making it difficult to debug issues, said Andy Kramolisch, AirBnB software engineer.
Airbnb will explain AirPal in greater detail March 19 at a Presto meetup on the Facebook campus in Menlo Park, California.
