5 Reasons Why Your Queue is Slowing You Down

If you're building complex products, you're probably using some sort of queueing system. Traditional queues help with scale, job scheduling, and managing background jobs — but as products become complex, traditional queuing systems start to fall short. While they work for basic message delivery and job processing, they often lack the higher-level abstractions required to build complex workflows. Things like workflow orchestration, multi-tenancy, and native throttling are being built into every product.

Developers require more than speed and storage; they need the flexibility to create custom workflows without getting tied down in complex infrastructure and protocols. Traditional queuing systems rely heavily on lower level abstractions, often leading to slow development time, complex operational overhead, and potential reliability issues.

Let's dive into the top 5 challenges modern teams typically face when building with traditional queues:

Problem 1: Juggling complex workflows

Managing complex workflows with traditional queues — such as passing data between multiple functions in sequence — can be a real challenge. Things can quickly become overwhelming when handling multiple queues, cron jobs, and complex application states.

These systems often lack native workflow orchestration, forcing you to piece together various tools and custom logic. This can make it difficult to monitor job performance and troubleshoot issues, especially when dealing with complex workflows involving multiple steps, conditional logic, and retries.

Traditional queuing systems treat each message as an isolated unit, making it challenging to track the overall progress of workflows and identify bottlenecks. This lack of visibility can significantly hinder troubleshooting efforts and impact overall system reliability. Even newer tools like Celery, while useful for task queuing and scheduling, still struggle with multi-queue workflows and require additional overhead for tracking, state management, and monitoring.

Inngest simplifies complex workflows by consolidating functions and steps into a single, intuitive system. With Inngest's Workflow Kit, you can define intricate processes in one workflow function with built-in scheduling features, eliminating the need to juggle queues, workers, crons, and database states. This streamlined approach accelerates development and simplifies workflow orchestration.

Problem 2: No built-in traffic cop

Traditional queues like Kafka, RabbitMQ, and Amazon SQS lack built-in traffic control mechanisms. This means you're left to manually implement solutions to manage the flow of messages, which can be a major pain point.

It's like trying to manually control a busy intersection with a LED stick. As applications evolve and scale, flow control becomes essential - something traditional queues don't offer out of the box. You're left to figure out how to implement solutions within these queues like native throttling, rate limiting, and job prioritization yourself across your workflows which can easily lead to bottlenecks, performance issues, and a lot of extra work.

Luckily, with Inngest's native flow control, you can say goodbye to the manual work associated with managing traffic flow. Inngest offers built-in throttling, debouncing, and dynamic prioritization, ensuring your system runs smoothly, efficiently, and fairly, even under heavy load.

Problem 3: Sharing the sandbox (and dealing with noisy neighbors)

Traditional queues often have limited support for multi-tenancy, making it difficult to share resources and control access across different environments. This can lead to “noisy neighbor” problems, where one tenant's heavy usage can impact the performance of others. (More on this issue in this article, if you're curious to learn more).

And if you were to make traditional queueing solutions work for multi-tenant use cases, it would mean a lot of extra work. Kafka users have to manage separate topics, partitions, and access controls for each tenant. RabbitMQ relies on creating virtual hosts with custom permissions. And SQS requires separate queues for each tenant. These workarounds can introduce security risks, scalability challenges, balloon your costs, and add significant complexity.

Inngest natively supports multi-tenancy eliminating the need for separate queues and complex permission setups for each tenant. With built-in, robust access controls, you can securely share resources across different environments without sacrificing performance or security.

Problem 4: Lost in the queue

Traditional queues also lack robust job management and recovery capabilities. While they're good at delivering messages, they don't always provide the visibility and control needed to ensure jobs complete successfully.

With RabbitMQ and Kafka, you're left to your own devices to track job progress, handle errors, and implement retries. And while on SQS you can get some monitoring with CloudWatch, it still requires custom solutions for job tracking and cancellation.

This lack of lifecycle management across jobs can lead to inefficiencies and wasted resources as jobs run unnecessarily or fail without a safety net. Inngest's native job management enhances your application by treating jobs as foundational elements, giving you greater control and visibility. Easily track statuses, cancel, re-run, and monitor jobs from start to finish, all within a single platform. Inngest also automates state management and recovery, ensuring reliable execution without manual intervention. Use Inngest's declarative cancellation, to automatically cancel functions based on system events, streamline your workflows and reduce operational overhead.

Problem 5: The black box of queues

Traditional queues often lack robust built-in observability tools. This means you must piece together external tools to monitor performance, troubleshoot issues, and optimize workflows.

For instance, while SQS integrates with Amazon CloudWatch, it's lackluster offering basic metrics (like the age of the oldest message and message count), it lacks detailed insights into message processing, latency, or advanced tracing. To gain deeper insights into processing latency, message tracing, or advanced debugging, you'll need to combine CloudWatch with custom logging or other AWS services.

Similarly, RabbitMQ and Kafka offer basic metrics, but often fall short when it comes to tracking latency or identifying bottlenecks in complex workflows. With RabbitMQ, you're often limited to basic metrics like message counts and queue lengths. While Kafka provides some metrics on consumer lag and partition offsets, it lacks deeper insights into message processing times and potential bottlenecks. To gain a clearer picture of your system's performance, you may need to rely on additional plugins or third-party tools like Prometheus or Confluent Control Center. All this extra tooling can add significant overhead and complexity to applications, making them harder to maintain and optimize.

With Inngest's comprehensive observability & metrics dashboard, you can say goodbye to the black box. Gain deep insights into workflow performance and issues, allowing you to troubleshoot faster, identify bottlenecks, and continuously optimize your system.
