GraalVM を普通の Java VM として使う ~クラウドベンチマークなどでの比較~Shinji Takao
?
クラウドや多言語の環境に対応できる 新しいJava実行環境 GraalVM は、ネイティブビルドだけでなく、通常の Java VM として使うこともできます。
このたび、クラウド環境用ベンチマーク「BluePerf」などを使い、GraalVM と OpenJDK を比較したので、結果を報告します。

This document discusses exactly once semantics in Apache Kafka 0.11. It provides an overview of how Kafka achieved exactly once delivery between producers and consumers. Key points include:
- Kafka 0.11 introduced exactly once semantics with changes to support transactions and deduplication.
- Producers can write in a transactional fashion and receive acknowledgments of committed writes from brokers.
- Brokers store commit markers to track the progress of transactions and ensure no data loss during failures.
- Consumers can read from brokers in a transactional mode and receive data only from committed transactions, guaranteeing no duplication of records.
- This allows reliable message delivery semantics between producers and consumers with Kafka acting as
This document provides an introduction and agenda for a session on migrating game server infrastructures to the cloud. It summarizes the experiences of Ubisoft and Behaviour Interactive in migrating their games Dead by Daylight and For Honor from peer-to-peer networking to using Amazon GameLift dedicated servers hosted on AWS. It also discusses how Gearbox Software developed online services for Borderlands 3 on AWS to support hundreds of millions of concurrent users at launch.
This document provides a list of links to various tools and services related to continuous integration (CI), integrated development environments (IDEs), project management, and Ruby platforms as a service (PaaS). It thanks the organizations behind these services and tools.
