Fixing noisy neighbor problems in multi-tenant queueing systems

Multi-tenant queueing systems can suffer from "noisy neighbor" problems where high volume users monopolize resources, causing delays for other users. Ensuring fairness and consistent performance for all users is crucial in such systems. Several approaches to solving this problem exist, but many require complex infrastructure management and custom worker logic. Inngest is a platform that provides built-in support for easily defining concurrency limits for each tenant, ensuring fairness without the overhead and complexity of traditional solutions. Concurrency controls can be defined within function configurations and applied to unique key values such as user ID or organization ID. This allows for flexible management of resources and workload prioritization in multi-tenant systems.
