SmartModules are programmable data streaming functions exposed to WebAssembly, allowing developers to manipulate data in real-time inside the Fluvio cluster without needing external services such as Lambda or Functions. SmartModules can be published to SmartModule Hub and downloaded to multiple clusters. Once downloaded, SmartModules can be chained together to build powerful data transformation pipelines.

InfinyOn Certified SmartModules published in the SmartModule Hub:

• Jolt - JSON to JSON transformation
• Json-Sql - JSON to SQL transformation
• RegEx - Regex filtering

Examples on how to use SmartModules in a pipeline:

• Build HTTP to SQL Pipeline
• Build MQTT to SQL Pipeline

SmartModule Development Kit smdk is a utility to generate, build, test, and publish SmartModules using Rust programming language. Install smdk through Fluvio CLI, and build your first SmartModule:

$ fluvio install smdk

$ smdk -h
