The purpose of this presentation is to showcase some tricks that will improve your code writing speed. Victor wants to help you to become faster to feel less guilty when you throw away some experiment, so you can then find the most simple design to solve your problem.

This talk is about the detailed analysis of how the process of reading from the Apache Cassandra database takes place in terms of performance, what are the stages of processing requests, how long they take, which threads are responsible for what.

Checkpointing in Java can help both legacy and cloud users. Christine will show you how to checkpoint a simple application and then restore it to one or several different machines.

Anna will tell about the approaches to restoring the expertise of systems using the example of fictional system written on Java and supporting technologies.

This talk will discuss things to consider when using JFR to profile hundreds of thousands of JVMs in mission-critical systems all over the world.

You're probably familiar with the well-known Garbage Collection policies such as CMS, G1, Shenandoah, ZGC, gencon, balanced, etc. This talk is meant to demystify some of these optimizations that even though might be transparent to a JVM user, makes a tremendous performance impact.

During the talk, we'll talk about how Netflix is using GraphQL and how they've found it to be useful.

In this talk, we will explore tooling and configuration options that get you to the fastest iteration in development (the "inner loop"), making use of all the newest features of Spring Boot, but also of the various tools from the Kubernetes community.

Babashka is a native Clojure interpreter for scripting. It is compiled to native using GraalVM native-image. In this talk, we will see how Babashka works internally through a live coding session.

With this talk, IntelliJ IDEA users will learn to make better use of their development tool.

A story about reducing roll-your-own solutions, choosing existing open source tools, and being humble in environments that often favor self-promotion over doing the right thing.

Every software developer knows, that you should use all static type system features in your API. Sometimes, though, you need to make an exception. But developers stumble on a mental block when such a case occurs. To avoid becoming a victim of such a situation, please listen to how enum is going to make your life miserable if used carelessly.

The talk about performance, or rather evidence and nuances around it, and about the code behaving unexpectedly and hidden gotchas behind very simple things.

We'll see how some language (and framework) design choices affect IDE features and performance.

Join Sebastian's live-coding session in Russian!

This session is a no-nonsense journey through the main reasons why Java 8 is no longer an acceptable solution — primarily for container deployments but the lessons are applicable more generally.

In this talk, Viktor will provide a brief overview of what limitations Zookeeper imposed on Kafka architecture, what will be changed, and the current status of Zookeeper removal.

This session will cover all of the new language features in Java since the last Long-Term Support release. We'll also cover the main new library APIs from small changes like the teeing collector to whole new libraries like the Foreign Function Interface.

Alexey will show what Spring Cloud components may be used in Kubernetes, how these projects complement each other, what they have in common. And finally, he will try to answer the question — what's the value of Spring in Kubernetes era?

This talk describes some of the workloads that have motivated the generational Shenandoah effort, provides an overview of the algorithms and heuristics that are being implemented and offers a summary overview of the work plan, including the most recent experimental results.

Why async/await is right for some lanugages but user-mode threads are better for Java (and others).

Do you want to understand how Spring Data works? Evgeny Borisov suggests writing analog to understand how Spring Data works.

In this talk, we will build a distributed multiplayer game system using RSocket and Spring that will host a popular game called Bomberman.

During this workshop, Andrei and Anton will demonstrate pair programming in action and write with you a simple app using TDD (so-called "ping-pong programming").

This session will introduce you to Helidon and Coherence Community Edition, summarize recent innovations and work in process, and demonstrate how to use these open source frameworks to build scalable REST, gRPC, and GraphQL microservices.

Do you want to understand how Spring Data works? Evgeny Borisov suggests writing analog to understand how Spring Data works.

Let's have a look at the benefits of pair programming in teams. Dmitry will show cases where you can use pair programming and what tasks it solves.

Alexander will talk about how and why Kotlin has been added to an enterprise project written in Java. This talk will explore technical problems encountered during the migration and the process of adoption of the new language by developers and managers.

We will talk about the schedule, sessions, and share the information. Join the broadcast to find out what's on the air soon!

The developers are always told to write texts and to be responsible for the quality. But is that true? During this session, we will try to dismember the testing pyramid, dig into the code and see where it takes us.

Alexey will tell you what you need to pay special attention to when writing code and developing your applications so that they become more secure and inaccessible to cyber villains.

We will talk about a microservice architecture approach to managing feature flags in a project using Apache Kafka.

BellSoft has integrated the new JEP into JDK16, added the Apple Silicon M1 Liberica JDK to the supported platforms, and released the new Liberica Native Image Kit product. Aleksandr Belokrylov will tell you how and by whom these products are created and what processes allow the company to remain open to the world community.

Anatoly will share his experience of using reactive frameworks to solve business problems in the field of creating voice assistants using the example of the orchestrator service, which is an entry point into the ecosystem for users of the Salyut family of voice assistants.

During this session, we will try to figure out whether everything is smooth with R2DBC, and what pitfalls may await us in the transition to this specification.

Компания JetBrains выпускает этой весной прицнипиально новую функциональность для всех своих продуктов — Code With Me. Это платформа для коллаборативной работы — неважно, парное ли это программирование, обучение классов, воркшопы, или mob-программирование. Какое значение это имеет для рядовых разработчиков и для IT-организаций? Как эта штука устроена внутри? Какая история и какое будущее у Code With Me? Обо всех этих вещах расскажет лид проекта, Кирилл Скрыган.

We live in a world where developers are required to have their systems process more and more information in less and less time. And so that the implementation of a new solution does not require much effort.
