Grant Henke commented on KAFKA-2076: ------------------------------------ This functionality and the edge cases that [~jkreps] mentioned was part of the motivation behind KIP-17: https://cwiki.apache.org/confluence/display/KAFKA/KIP-17+-+Add+HighwaterMarkOffset+to+OffsetFetchResponse Perhaps the title of that KIP should be made more generic, and the content adjusted, and the discussion around this can happen there? > Add an API to new consumer to allow user get high watermark of partitions. > -------------------------------------------------------------------------- > > Key: KAFKA-2076 > URL: https://issues.apache.org/jira/browse/KAFKA-2076 > Project: Kafka > Issue Type: Improvement > Reporter: Jiangjie Qin > > We have a use case that user wants to know how far it is behind a particular > partition on startup. Currently in each fetch response, we have high > watermark for each partition, we only keep a global max-lag metric. It would > be better that we keep a record of high watermark per partition and update it > on each fetch response. We can add a new API to let user query the high > watermark. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
