Rule Engine Introduction

Use the feature of rule engine to forward the data information in Topic to other Topic or other products of Baidu AI Cloud for storage or processing.

Currently, the rule engine is in the stage of open Beta test, and the message failure caused by rule engine is not included in the IoT cores suit SLA. Please submit a ticket for feedback in case of any problem encountered during the use.

What is a rule engine

When devices communicate based on Topic, we can write SQL in the rule engine to convert and process data in Topic and configure forwarding conditions to filter and forward the processed data to Topic of other devices or other services of Baidu AI Cloud.

E.g.:

• Forward the data to the Topic of another device to realize the M2M communication between device and device.
• Forward the data to the Time Series Database TSDB for storage.
• Forward to Baidu Messaging System (BMS) (fully compatible with Apache Kafka), and then use real-time computing for traffic computing, use big data tools for large-scale offline computing, or realize highly reliable consumption data of business application.

After using the rule engine feature, you do not need to purchase server to deploy distributed architecture, and can realize the full-stack all-data link service integrating collection + computing + storage.

Usage limits for rule engine

• The rule engine processes the date based on Topic. Data flow can be used only upon communication via Topic.
• The current version only supports filtration and query for the data reported with JSON format.
