-------------------------------
As a potential solution why can't the {{OffsetStorageWriter}}'s {{void
offset(Map<String, ?> partition, Map<String, ?> offset)}} function be made
available on the {{SourceTaskContext}}? This seems to me as if it would work
out of the box... or am I missing something?
Additionally offsets need to be written in {{WorkerSourceTask}} after
{{transformationChain.apply}} if it returns {{null}} indicating that the record
should be filtered.
> Allow Kafka Connect source tasks to produce offset without writing to topics

> 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.
