Conor Hughes commented on KAFKA-4373: ------------------------------------- Thanks for such a the quick reply! After you mentioned log retention policy I went back through my kafka configurations and noticed log.retention.hours was set back to the default 7 days (168 hours). The trace files I was using were from over a month ago so messages were being deleted every 5 minutes as the were older than 7 days. (Note: I'm using a custom timestamp extractor) > Kafka Consumer API jumping offsets > ---------------------------------- > > Key: KAFKA-4373 > URL: https://issues.apache.org/jira/browse/KAFKA-4373 > Project: Kafka > Issue Type: Bug > Components: consumer > Reporter: Srinivasan Venkatraman > > Hi, > I am using Kafka Version 0.10.0.1 and java consumer API to consume messages > from a topic. We are using a single node kafka and zookeeper. It is sometimes > observed that the consumer is losing a bulk of message. We are unable to find > the exact reason to replicate the issue. > The scenario is: > Consumer polls the topic. > Fetches the messages and gives it to a thread pool to handle the message. > Waits for the threads to return and then commits the offsets. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
