Feature Overview

AWS IoT Integration

  • AWS Iot Ready — Bring your own cloud.
  • Capture device data and export to AWS.
  • Send control plane data to AWS IoT shadows.
  • Transparent database synchronization with AWS DynamoDB.
  • Stream volume device data to AWS S3 data lake or Kinesis.
  • Store device logs, metrics in AWS CloudWatch.
  • Keep an audit trail in CloudTrail.

MQTT Client

  • MQTT 3.1.1 support.
  • TLS encryption with ALPN over port 443.
  • Supports connect, publish, subscribe, ping and disconnect messages.
  • Message quality of service for reliable delivery.
  • Retained messages.
  • High message throughput with exceptionally low overhead.
  • Wait for delivery or acknowledgement options.
  • Auto reconnect.
  • Parallelism via fiber coroutines.

DynamoDB Local Database

  • High performance in-memory NoSQL management document database.
  • Red/black binary search indexes.
  • JSON documents with in-memory query API.
  • Controllable persistency locally and to the cloud on a per-table basis.
  • Transparent bi-directional data synchronization with DynamoDB in the cloud. (like Global Tables).
  • Unified data schema between device and cloud databases.
  • Based on DynamoDB OneTable API.
  • Use DynamoDB OneTable API.

HTTP Server

  • HTTP/1.0, HTTP/1.1 support.
  • TLS/SSL 1.3 and Alpn support.
  • URL actions that bind URLs to C functions.
  • Configurable request routes and redirections.
  • Supports transfer chunk encoding to preserve keep-alive.
  • Cookie and session management.
  • Authentication and user management.
  • Fully streaming API for dynamic input and output.
  • Request tracing for HTTP request and response headers.
  • Sand-box resource limits.
  • Runtime configurable via JSON config files.
  • HTML helpers for encoding, decoding and escaping content.
  • JSON parser and query engine.
  • Single-threaded, fiber coroutine event-based runtime.

HTTP Client

  • HTTP/1.0, HTTP.1.1 client.
  • Fully streaming API for dynamic input and output.
  • Convenience JSON API for interacting with REST services.
  • Single-threaded, fiber coroutine event-based runtime without ugly callbacks or complex threads.
  • TLS/SSL 1.3 with certificate verification controls.

JSON Parser and Engine

  • JSON and JSON/5 support.
  • JSON parser and renderer.
  • JSON query engine.

Safe Runtime

  • Fiber coroutines for non-blocking procedural programming model.
  • Global memory error handler.
  • Networking and TLS support.
  • Logging framework —— filter by source and/or message type.
