Randall Hauch commented on KAFKA-3821:
--------------------------------------
[~criccomini] logged KAFKA-5084, but that is really another situation where the
connector would like to provide new offsets without having to produce
{{SourceRecord}}. As he says
[here|https://confluentcommunity.slack.com/archives/C49L0V3L7/p1492547735471505],
the connector sometimes need to tell Kafka Connect:

> Allow Kafka Connect source tasks to produce offset without writing to topics

> Key: KAFKA-3821
> URL: https://issues.apache.org/jira/browse/KAFKA-3821
> Project: Kafka
> Issue Type: Improvement
> Components: KafkaConnect
> Affects Versions: 0.9.0.1
> Reporter: Randall Hauch
> Labels: needs-kip
>
> Provide a way for a {{SourceTask}} implementation to record a new offset for
> a given partition without necessarily writing a source record to a topic.
> Consider a connector task that uses the same offset when producing an unknown
> number of {{SourceRecord}} objects (e.g., it is taking a snapshot of a
> database). Once the task completes those records, the connector wants to
> update the offsets (e.g., the snapshot is complete) but has no more records
> to be written to a topic. With this change, the task could simply supply an
> updated offset.
