Summary: KIP-31 (part 1): Add timestamp field to message, configs,
and Producer/ConsumerRecord
Key: KAFKA-3025
URL: https://issues.apache.org/jira/browse/KAFKA-3025
Project: Kafka
Issue Type: Improvement
Reporter: Anna Povzner
Assignee: Anna Povzner
This JIRA is for changes for KIP-32 excluding broker checking and acting on
timestamp field in a message.
This JIRA includes:
1. Add time field to the message
Timestamp => int64
Timestamp is the number of milliseconds since Unix Epoch
2. Add time field to both ProducerRecord and Consumer Record
If a user specifies the timestamp in a ProducerRecord, the ProducerRecord is
sent with this timestamp.
If a user does not specify the timestamp in a ProducerRecord, the producer
stamps the ProducerRecord with current time.
ConsumerRecord will have the timestamp of the message that were stored on
broker.
3. Add two new configurations to the broker. Configuration is per topic.
* message.timestamp.type: type of a timestamp. Possible values: CreateTime,
LogAppendTime. Default: CreateTime
* max.message.time.difference.ms: threshold for the acceptable time difference
between Timestamp in the message and local time on the broker. Default:
Long.MaxValue
