Amazon Athena Engine Upgrades, Support for Lambda Expressions, and Ability to Skip Headers

Amazon Athena uses Presto, an open source distributed query engine, to run SQL queries against data in Amazon S3. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries you run. We are happy to announce that we have transparently updated Athena's underlying engine to a version based on Presto 0.172.
