Feed: AWS Compute Blog. Author: Benjamin Smith. This post is written by Mark Sailes, Senior Specialist Solutions Architect. This blog post shows how to optimize the performance of AWS Lambda functions written in Java, without altering any of the function code. It shows how Java virtual machine (JVM) settings affect the startup time and performance. You also learn how you can benchmark your applications to test these changes. When a Lambda function is invoked for the first time, or when Lambda is horizontally scaling to handle additional requests, an execution environment is created. The first phase in the execution environment’s ... Read More

Feed: AWS Big Data Blog. Our customers use Apache Hive on Amazon EMR for large-scale data analytics and extract, transform, and load (ETL) jobs. Amazon EMR Hive uses Apache Tez as the default job execution engine, which creates Directed Acyclic Graphs (DAGs) to process data. Each DAG can contain multiple vertices from which tasks are created to run the application in parallel. Their final output is written to Amazon Simple Storage Service (Amazon S3). Hive initially writes data to staging directories and then move it to the final location after a series of rename operations. This design of Hive renames ... Read More
