Query: Triggerflow: Trigger-based Orchestration of Serverless Workflows   As more applications are being moved to the Cloud thanks to serverless
computing, it is increasingly necessary to support native life cycle execution
of those applications in the data center. But existing systems either focus on
short-running workflows (like IBM Composer or Amazon Express Workflows) or
impose considerable overheads for synchronizing massively parallel jobs (Azure
Durable Functions, Amazon Step Functions, Google Cloud Composer). None of them
are open systems enabling extensible interception and optimization of custom
workflows. We present Triggerflow: an extensible Trigger-based Orchestration
architecture for serverless workflows built on top of Knative Eventing and
Kubernetes technologies. We demonstrate that Triggerflow is a novel serverless
building block capable of constructing different reactive schedulers (State
Machines, Directed Acyclic Graphs, Workflow as code). We also validate that it
can support high-volume event processing workloads, auto-scale on demand and
transparently optimize scientific workflows.
