Summary: Trogdor - Improve RoundTripWorker Key: KAFKA-7819 URL: https://issues.apache.org/jira/browse/KAFKA-7819 Project: Kafka Issue Type: Improvement Reporter: Stanislav Kozlovski Assignee: Stanislav Kozlovski Trogdor's RoundTripWorker task has a couple of shortcomings: * Consumer GroupID is hardcoded and consumers use `KafkaConsumer#assign()`: [https://github.com/apache/kafka/blob/12947f4f944955240fd14ce8b75fab5464ea6808/tools/src/main/java/org/apache/kafka/trogdor/workload/RoundTripWorker.java#L314] Leaving you unable to run two separate instances of this worker on the same partition in the same cluster, as the consumers would overwrite each other's commits. It's probably better to add the task ID to the consumer group * the task spec's `maxMessages` [is an integer|https://github.com/apache/kafka/blob/12947f4f944955240fd14ce8b75fab5464ea6808/tools/src/main/java/org/apache/kafka/trogdor/workload/RoundTripWorkloadSpec.java#L39], leaving you unable to schedule long-winded tasks * the consumer and producer are not closed gracefully when the task ends -- This message was sent by Atlassian JIRA (v7.6.3#76005)
