Micah Ramos created KAFKA-9584: ---------------------------------- Summary: Removing headers causes ConcurrentModificationException Key: KAFKA-9584 URL: https://issues.apache.org/jira/browse/KAFKA-9584 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 2.0.0 Reporter: Micah Ramos
The consumer record that is used during punctuate is static, this can cause java.util.ConcurrentModificationException when modifying the headers. Using a single instance of ConsumerRecord for all punctuates causes other strange behavior: # Headers are shared across partitions. # A topology that adds headers could append an infinite number of headers, causing memory problems in the current topology as well as down stream consumers since the headers are produced when the records is produced to a topic. -- This message was sent by Atlassian Jira (v8.3.4#803005)
