             Summary: Support Share Groups (Queue Semantics) in Kafka Connect Sink Connectors
                 Key: KAFKA-20367
                 URL: https://issues.apache.org/jira/browse/KAFKA-20367
             Project: Kafka
          Issue Type: New Feature
          Components: connect, consumer, group-coordinator, kip
            Reporter: Shekhar Prasad Rajak
            Assignee: Shekhar Prasad Rajak


Introduce Share Group support in Kafka Connect sink tasks via a new WorkerShareSinkTask, enabling queue semantics (record-level distribution, no rebalances) with config-only opt‑in. 

At‑least‑once is default; 
exactly‑once is supported only for same‑cluster Kafka‑to‑Kafka when KIP‑1289 transactional share acknowledgments are available. 

Error handling uses RELEASE for retriable failures and REJECT for fatal failures; when KIP‑1191 is enabled, broker‑side DLQ is the sole DLQ source (Connect does not emit its own DLQ records in Share Group mode).
