Clojure has powerful concurrency primitives, but they don’t always play nicely with side-effects. Services that take a single input and produce a single output can be easily modeled as functions, but more complicated relationships between input and output lack a first-class representation in the language.

This talk will explore a potential solution: Lamina, which provides abstractions for event-driven workflows, and Aleph, which uses these abstractions to model network communication over a variety of protocols.

Topics will include:

• A survey of event-driven programming, discussing the benefits and shortcomings of various approaches
• An abstraction that models events as streams of messages, allowing familiar operations such as map, filter, and reduce
• Building upon these streams to create complex asynchronous workflows
• Using these abstractions to create sophisticated, performant network services with minimal boilerplate and ceremony
