Abstract

Serverless computing, also known as the Function-as-a-Service (FaaS) paradigm, has become a cornerstone of modern cloud-based applications, enabling developers to build and execute workflows by composing server-less functions. However, current serverless platforms are limited by constrained orchestration and function composition capabilities, which reduce their expressiveness and performance. To address these limitations, this paper introduces three enhancements to Apache OpenWhisk: native support for currying, continuation, and Directed Acyclic Graphs (DAGs). These enhancements are designed to improve the expressiveness of serverless workflows, reduce latency, and enable partial execution of dynamic workflows as soon as data becomes available.
