Major Changes

• Redesigned Architecture and Stack

  • Complete architectural overhaul
  • New stack implementation

• Simplified Architecture Configuration

  • Replaced sizing options with direct choice between Concentrated and Distributed architectures
  • Moved detailed configuration parameters to architecture.ts for better clarity and control

• Context Broker Update

  • Upgraded Scorpio Broker to version (5.0.90)

• Improved Ingestion Process

  • Eliminated AWS IoT Device Shadow dependency
  • Implemented direct ingestion via deployment-provided queue
  • Added automatic context broker updates using batch operation upsert
  • Delivered more cost-effective and scalable solution

• Database Engine Update

  • Aurora Serverless v2 upgraded to PostgreSQL v16.6

• Streamlined Data Lake Integration

  • Direct Kinesis Firehose integration for data lake delivery
  • Created more efficient data pipeline by removing IoT rule dependency

• API and Data Model Changes

  • Removing the Garnet JSON-LD context
  • Deprecation of IoT API
  • Authorization now enforced with a token (provided as output of CloudFormation stack)
  • JSON-LD context change: AWS IoT thing is now referenced as AwsIotThing

• NGSI-LD Type for Things changed. Now AWS IoT thing is AwsIotThing.

Required Actions

Users will need to:

• Update their ingestion workflows to use the new queue for ingesting
• Migrate any AWS IoT Device Shadow dependencies

1.3.0

[1.3.0] - 2024-05-07

This new version fixes a bug we had due to the use of SQS in Scorpio Broker for fanning out messages. This led to missing messages in the datalake, the temporal storage and the subscriptions.

[1.3.0] - Added

• SNS for fanning out messages to dedicated SQS queues per service.
• VPC endpoints for SNS and SQS

[1.3.0] - Changed

• Updated Aurora serverless v2 engine version to Postgresql v15.5

1.2.0

This releases fixes some bugs, introduces new features and potential breaking changes.

• Distributed architecture. You can now deploy Garnet using the microservice version of Scorpio Broker.
• T-shirt Sizing for deployment. You can now choose the size of the deployment between Small and Xlarge depending on your workload.
