Description
Fixes #1506
The package confluent-kafka has a class Consumer, which has a method called commit (Ref: https://docs.confluent.io/platform/current/clients/confluent-kafka-python/html/index.html#confluent_kafka.Consumer.commit)
The package opentelemetry-instrumentation-confluent-kafka offers a wrapper around confluent-kafka's Consumer, called ProxiedConsumer. However ProxiedConsumer does not support
commit
method. This leads to an exception with the message "Consumer closed" when ProxiedConsumer.commit is called.This PR fixes this by adding a method
commit
on ProxiedConsumer, which accepts the same args as confluent-kafka's Consumer's commit method and makes a call to that method.Type of change
Please delete options that are not relevant.
How Has This Been Tested?
Previously calling
commit
on the ProxiedConsumer would lead to an exception. With the changes in this PR, callingcommit
ensures the message is committed since it calls the underlying Consumer's commit method.Does This PR Require a Core Repo Change?
