Explore a conference talk on Rembus.jl, a Pub/Sub and Remote Procedure Call middleware for Julia, presented by Attilio Donà at JuliaCon 2024. Learn about this tool designed for microservices-oriented enterprise systems, focusing on simplifying distributed application implementation, optimizing performance, and supporting both broker and broker-less architectures. Discover how Rembus leverages Julia's metaprogramming capabilities to offer a novel API approach for transforming functions into "distributed" functions. Gain insights into Pub/Sub patterns with examples of publishers and subscribers, and understand how Rembus facilitates the exchange of primitive types, binary data, and DataFrame objects between components. The talk covers motivations behind Rembus, its main features, fault-tolerance capabilities using Visor.jl, implementation examples for pub-sub and RPC systems, and includes a demo on exchanging dataframes between Julia, Python, and Rust.
