Matthew Tieman created STORM-697: ------------------------------------ Summary: Support for Emitting Kafka Message Offset and Partition Key: STORM-697 URL: https://issues.apache.org/jira/browse/STORM-697 Project: Apache Storm Issue Type: Improvement Components: storm-kafka Reporter: Matthew Tieman Assignee: Matthew Tieman
It would be nice expose the offset and partition of messages consumed from Kafka to the Scheme generating the Tuples. This is useful for auditing/replaying data from arbitrary points on a Kafka topic. There are a few ways to accomplish this. One is to define a new extension of Scheme, say MessageAndMetadataScheme, and add another case in KafkaUtils.generateTuples to determine if the config's schema is an instance of MessageAndMetadataScheme. Another is add a flag to SpoutConfig indicating that the scheme should accept a byte array of MessageAndRealOffset. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
