New CJUG Meeting Announced! Paul Nauman Presents: How NOT to Measure Latency
Abstract: Latency is an important aspect of performance for many applications. However, there are many common mistakes and misunderstandings that people make when measuring and evaluating application latency. In this talk we'll dicuss what latency is, when it is important, and why. We'll look at common latency assessments and see what they really mean for likely observed application performance. We'll discuss Coordinated Omission, an extremely common measuring error that can significantly distort latency data, and lead to erroneous conclusions and decisions. We'll also see how latency is a particular problem for Java and for common Java application areas like web technologies. Finally we'll also introduce some tools and techniques that can help measure and mitigate latency.

Bio: Paul is a Principal Sales Engineer at Azul. He was previous a member of the JVM Sustaining Engineering organization at Oracle Corp. Paul has also worked for Sun Microsystems, Ameritech and Bell Laboratories. Paul has an extensive background in system-level programming in telecommunications and financial services.

New CJUG Meeting Announced! Arun Gupta Presents: Full-stack NoSQL Document Database
Abstract: Couchbase Server is an open source, document-oriented NoSQL database. It can be installed in your data center or mobile platform. The database is designed for ease of development and low latency at scale. As a mobile database, it has everything you need to build always-available apps that work online & offline.This session will provide an introduction to Couchbase Server. Attendees will learn how they can easily store and access data in Couchbase using N1QL - SQL for JSON. The data can also be persisted using APIs from different languages. They'll learn how a Couchbase cluster can be easily created and scaled. Integration with multiple frameworks such as Spring Data, Spark, and Kafka will be discussed. Managing database using CLI, admin console and REST will be explained. Deployment options in Cloud and Containers will be discussed and shown. The second part of the session will provide an introduction to Couchbase Mobile. It will explain the key features of fully functional, embedded, mobile NoSQL database. Attendees will learn how write apps faster using less code by taking advantage of database change events from Couchbase Lite. See how just a few lines of code enables app developers to synchronize data between multiple devices using Sync Gateway. Bio: Arun Gupta is vice president of developer advocacy at Couchbase. He has built and led developer communities for more than 10 years at Sun, Oracle, and Red Hat. He has deep expertise in leading cross-functional teams to develop and execute strategy, and planning and ex*****on of content, marketing campaigns, and programs.
