Amazon AWS Athena

Amazon Athena is an analytics service that makes it easy to get insights from Amazon S3-based data lakes, using open standards including SQL Parquet, Apache Iceberg, and others. Athena is serverless, so there is no infrastructure to set up or manage as the service automatically scales for arbitrary large datasets and complex queries. Creating a simple, rich, and performant customer experience requires solving challenging engineering problems. We are working on our own container and scale-out infrastructure (forecasting, scheduling, containers, admission control, infrastructure deployment) and making significant contributions and improvements to the Presto/Trino Open Source engine to add more capabilities (updates, secondary indices, materialized views, better scripting support). At the same time, we are improving its performance and reliability (memory management, micro-optimizations, CBO, and vectorization).
