Amazon Database Engineer Open Data Analytics Engines - Spark Engine Performance 

Japan 

51030212

Athena and EMR are services that our customer use to run large scale analytics, leveraging open source engines like Trino and Spark. The analytic engine organization makes significant modifications to these engines to run in serverless environments and with superior performance and scalability than what is available in Open Source. In the last 3 years we have improved our engines by a factor of 5x by making changes to the optimizer, query runtime and storage connectors. We have also made significant changes to the compiler to enable enterprise features like fine grain access control. This is a “must-win” strategic area in a growing and very technical space.
