Difficult to bridge between OpenCensus, OpenTracing and OpenTelemetry. As OpenTelemetry is has superseded OpenCensus and OpenTracing, leverage that to reduce the complexity.

Describe the solution you'd like

This needs a design doc if we choose to do it.

An update on this topic from the census-instrumentation/opencensus-java repository:

OpenCensus and OpenTracing have merged to form OpenTelemetry, which serves as the next major version of OpenCensus and OpenTracing.

OpenTelemetry has now reached feature parity with OpenCensus, with tracing and metrics SDKs available in .NET, Golang, Java, NodeJS, and Python. All OpenCensus Github repositories, except census-instrumentation/opencensus-python, will be archived on July 31st, 2023. We encourage users to migrate to OpenTelemetry by this date.

OpenCensus is rolling an outdated version of io.grpc:grpc-context which causes a dependency convergence error when pulling in the google-http-client as a dependency, which I suppose is going to stop a lot of upgrades:

Error:  Dependency convergence error for io.grpc:grpc-context:jar:1.60.1 paths to dependency are:

Hello,

Is there any future work planned on this? OpenTelemetry has come a long way and OpenCensus is retired in favor of OpenTelemetry.

noting #834 (and that this obsoletes #621)

[jonatan-ivanov]

You might want to consider this so that you can use tracing/metrics/etc. libraries through a common API/abstraction and use whatever implementation you/your users want under the hood:

Hello Team,

Is there any update on replacing OpenCensus with OpenTelemetry?
Is this task currently under development?
If yes, can you please provide a rough ETA for this release please?

[blakeli0]

Hey @SamsonChris71, there is no active development regarding OpenTelemetry in this repo at this moment.

@lesv @blakeli0 Note that Opencensus repos have now been archived in GitHub:

All OpenCensus Github repositories, except census-instrumentation/opencensus-python, will be archived on July 31st, 2023. We encourage users to migrate to OpenTelemetry by this date.

Even if OTEL isn't added, it's really time to remove a totally unmaintained and archived dependency from this client (better doing now than when an eventual CVE in OpenCensus that won't be fixed forces the issue).
