Micronaut Requirements

Minimum Feature Set

The following features are a TODO list of things to do on Micronaut before launching

Core Features

Documentation Generation

• We should generate asciidoc documentation for @ConfigurationProperties

• Add generic annotated type visitor API to allow generating OpenAPI doc

Aspect Implementations

We need to implement AOP annotations for:

• Spring @Transactional

Configuration Sharing

Need a mechanism for configuration discovery and sharing across the federation. Configuration sharing should initially support:

• AWS Systems Manager Parameter Store (https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-paramstore.html and Example https://gist.github.com/ariesmcrae/b72aa0f986f87977ffc2de42481c8885)

Auto Configurations and Health Checks

We still need auto-configurations for the following:

• Apache Kafka (ivan)

• Cassandra (nero)

• RabbitMQ (ben)

Security / JWT Token Solution

Need to implement support for JWT token based authorization

Management Features

Tasks to complete:

• Endpoints shouldn’t be exposed to the web by default

• Integrate Endpoints with Security solution above such that @Endpoint.defaultSensitive is honoured

• Add support for JMX

Endpoints

We need endpoints for managing and/or exposing information about:

• logging

These should be built on the Endpoint API.

HTTP Server

Content Negotiation

Content negotiation must be supported

WebSocket Support

WebSocket Support must be implemented

HTTP Client

• Connection Pooling

• Server Sent Events

• CONTINUE request handling

Distributed Tracing

Built in distributed tracing should be activated by default and allow integration with third-party tools (zipkin, opentracing etc.).

Metrics

Built in metrics support on-top of Micro Meter (jack)

File Upload Features

• Add support for @Size on blocking types that receive multipart data. Should override the global setting

• Support multiple form data parts with the same name

CLI

Profiles

• Function/Lambda (serverless)

Features

• Http Client

• Tracing

• Mongodb

• GORM

Commands

• Create Controller

• Create Test

• Create Job (@Scheduled)

POST 1.0 Items

The following items are postponed until after 1.0

HTTP/2 Support

• The HTTP server should support HTTP/2

Configuration Sharing

• Google Cloud Runtime Configurator (https://cloud.google.com/deployment-manager/runtime-configurator/reference/rest/)

Service Discovery

• Amazon Route 53 (see https://docs.aws.amazon.com/Route53/latest/APIReference/overview-service-discovery.html)

• Google Cloud Metadata Server (see https://cloud.google.com/compute/docs/storing-retrieving-metadata?hl=en)

HTTP Gateway

An HTTP gateway that loads on port 8080 and uses the aforementioned HTTP client. The gateway need to be responsible for:

• JWT Token based authentication

• Load Balancing

• Starting Distributed Tracing

• Retry

• Rate limiting

• Route matching on HTTP Request (Path, Method, Header, Host, etc…​)

• Filters to modify downstream HTTP Request and HTTP Response (Add/Remove Headers, Add/Remove Parameters, Rewrite Path etc…​)
