Schema transformation tooling

1. Schemaprocessor in collector-contrib. It's a stub and does not do anything. It's not included into collector-contib image.

2. Search for https://opentelemetry.io/schemas/ does not show if anyone uses transformation logic.

3. There is no schema transformation logic in exporters in opentelemetry-collector-contrib repo.

4. There is a schema parser https://pkg.go.dev/go.opentelemetry.io/otel/schema/v1.1

Settlement in messaging systems

Proposal

Attributes:

• is there a need in generic?
• messaging.settlement.settled: boolean

System-specific:

• messaging.kafka.committed.offset
• messaging.rabbitmq.ack.type, messaging.rabbitmq.ack.delivery_tag

Kafka

• Host: net.peer.name:net.peer.port (actual host contacted)
  • always present
• Topic name: messaging.destination.name
  • maybe present per message, not per publish call - https://stackoverflow.com/questions/39093488/can-single-kafka-producer-produce-messages-to-multiple-topics-and-how

Metrics in Azure SDK for Java

The immediate goal is to report metrics from Azure messaging SDKs (EventHubs and ServiceBus) to help customers detect and investigate configuration issues, performance bottlenecks, application and SDK bugs.

It can be broken down into smaller goals:

• define metrics essential for messaging scenarios
• define Metrics API in azure-core
• metrics plugin implementations

Quarkus configuration

Quarkus configuration is very similar to Spring:

• supports application.properties and application.yaml
• conventions on property names are the same: '.' as separator, kebab-case.
• supports property sources, iterating over them and getting value by name programmatically or with annotation

What's different:

• Quarkus uses smallrye-config which is implementation of microprofile-config. Annotation and feature-wise, it's similar to spring, but more explicit (reflection is discouraged)
• Property metadata can be extended with microprofile language-server extension (example)
