Presentation: Asynchronous API With CompletableFuture
Share this on:
What You’ll Learn
- Performance tips for async particularly about java.util.concurrent.CompletableFuture.
- Pitfalls to async development.
Abstract
Since Java 8, CompletableFuture has enabled asynchronous, future-based programming in Java and is one of the most powerful features suitable for creating asynchronous APIs. This presentation, based on real project experience, goes beyond the CompletableFuture public API. It reveals internal details and shows who stands to benefit from it for better performance.
Interview
Making things faster is my primary goal. Not only by measuring not only providing some performance guidance, but also working on different projects.
At some moment I decided to make a presentation which will show the real performance job - how I took some project (It was new HttpClient appeared in Java9) and worked on its performance from scratch. The presentation become too big, so I split it into two parts: performance of synchronous API and performance of asynchronous. I think that problems which I discovered, how I improved will be interesting for the audience.
Intermediate to advanced Java developers who want to understand how async architectures and development strategies work.
Learning how to properly use async and CompletableFuture class to develop reliable fast code.
What bothers me is the fact that technology is changing quite fast and how fast we should run or just adjust our tools our current tools and methodologies for new technologies for example.
Even a couple years ago everybody start talking about cloud etc. and nobody knows how to properly measure and estimate performance inside clouds.
