--------------------------------------------
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).
