haibow commented on issue #4172: Kafka Low Level Consumer (LLC) Offset Lag metrics URL: https://github.com/apache/incubator-pinot/issues/4172#issuecomment-501546577 @sunithabeeram thanks for the clarification. Will look into this. w.r.t. freshness, how would you handle topics with low traffic rate (e.g. 1 message per 10s minutes, or just no data for a while)? Now we have alerts set up on ingestion lags; if we were to alert on this 'freshness' metric, sounds like false alarms are possible if freshness thresholds are not carefully tuned.
