It’s always good if our attributes/semantic conventions align with existing C# driver OpenTelemetry support: https://docs.datastax.com/en/developer/csharp-driver/3.22/features/opentelemetry/index.html#attributes And of course the OpenTelemetry official Cassandra semantic conventions: https://opentelemetry.io/docs/specs/semconv/database/cassandra/
We are developing OpenTelemetry support on the Java driver side, aiming to release in v4.20.0. We would love to align with your work, too.

It would be good to understand the plan for those as part of this CEP?

The original draft of the proposal was integrating not only tracing but also metrics and logs, however, the latest proposal reduced the scope so we can get started in integrating OpenTelemetry standard. I'd like the opinion in 4 topics below: * How to configure OpenTelemetry * The way of propagating Context * Resource definition to describe Apache Cassandra node as a telemetry source * Span creation and its attributes Regards, Yuki 1: https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-32%3A+OpenTelemetry+tracing+integration<https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-32%3A+OpenTelemetry+tracing+integration >
