Data is being produced everywhere, there are sensors in thousands of homes, metrics collection from your cloud applications, industrial sensors manage the safe provision of water and electricity. The question is, what do we do with all of this data? How do you cope with thousands (or millions) of push-based data events per second?

A crucial part of any of any solution is to have the right primitives. An asynchronous, push-based event processing pipeline is essential. OSGi Push Streams offer the power and simplicity of Java 8 streams, but with the power of asynchronous push-based events. This talk will describe the  work happening in OSGi's Push Streams RFC, using streams and promises to build scalable event processing pipelines.

Background

The OSGi service platform has existed as a modular micro-service runtime for well over a decade, but more recently it has embraced asynchronous programming as a core part of the OSGi toolkit. With the introduction of the Async Service, and OSGi promises it is now easier than ever to build asynchronous applications. The focus so far has been on asynchronous requests, but what about streaming systems, ones that need to process or filter thousands,  millions, or billions of events before an answer is reached, or perhaps there is no end to the stream at all!

Processing distributed events is the purpose of the Distributed Eventing RFC being discussed by the OSGi Enterprise Expert Group. As the lead author of the RFC, and the lead of the Asynchronous Service specification, Tim has a detailed understanding of the complexities of Asynchronous programming models. Tim will be able to describe the current prototyping around OSGi's Asynchronous Streaming model, and how it fits with the other popular asynchronous standards.
