Queues

Overview

In ThingsBoard, queues guarantee the message processing, handle occasional spikes, and keep the system up and running on extreme loads. Edge Queues are designed in the same way as Platform (Cloud) Queues. For a better understanding, read the Platform Queues documentation.

Tenant administrators can use any queue in the Edge Rule Chain, the same as the Platform Rule Chain. Queues can be used in checkpoint node or any analytics nodes (for a Professional Edition).

Starting with Edge 3.9, Edge supports Kafka and in-memory types of message queues:

• In-Memory: The built-in and default queue implementation. It is useful for development or proof-of-concept (PoC) environments, but is not recommended for production or any type of clustered deployments due to limited scalability.
• Kafka: A widely used, distributed, and durable message queue system designed to handle large volumes of data. It is well-suited for production environments where high throughput, fault tolerance, and scalability are critical.

All queues are created on the Platform and automatically propagated to each Edge instance connected to the Platform. Only a system administrator user can configure queues. After configuration, new changes will apply immediately. No additional assignment actions are required by tenant administrator or user.

In the current release, you cannot create, modify, or delete queues on the Edge.
