-------------------------------------
Summary: [runtime][rpc][metrics] Expose RPC response frame size
and oversized-response rejection metrics
Key: FLINK-39160
URL: https://issues.apache.org/jira/browse/FLINK-39160
Project: Flink
Issue Type: Improvement
Components: Runtime / RPC
Affects Versions: 2.2.0
Reporter: Arun Lakshman
Flink currently lacks metrics for RPC-level observability for serialized
response frame sizes and oversized-response rejections. When responses exceed
pekko.framesize, they are rejected, but we cannot easily see the response-size
trend. This makes it difficult to diagnose RPC failures, tune frame-size
settings, and detect payload-size regressions in production
