描述

What would you like to happen?

Currently in KafkaCommitOffset.CommitOffsetDoFn there is no visibility into how often offset commits are failing or how many retries are being attempted. If commits are silently failing in production you have no way to know without digging through logs. Adding Beam metrics here would make it easy to monitor commit health through existing monitoring dashboards. Proposed approach

Add a counter for total commit failures Add a counter for retry attempts Add a counter for commits that exhausted all retries Use Beam's built in Metrics.counter() so it works with any runner

Why this is useful If you're running a high throughput pipeline and offset commits are struggling, right now you'd have no idea until you see duplicate processing. This gives you an early warning signal.

研究方向
The implementation should be in the Java SDK's Kafka IO connector, specifically in the `KafkaCommitOffset.java` file within the `CommitOffsetDoFn` class. Examine the existing commit logic to identify where failures and retries occur. Use Beam's `Metrics.counter()` to add counters for total failures, retry attempts, and exhausted retries. The issue has no linked PRs or assignees, so it is available for contribution.
