# Summary NIFI-15961 - Add Kafka share-group support to ConsumeKafka Introduce share-group consumption for ConsumeKafka backed by Kafka 4.2's GA share consumer ([KIP-932](https://cwiki.apache.org/confluence/display/KAFKA/KIP-932%3A+Queues+for+Kafka)). A new "Group Type" property selects between the existing classic Consumer Group code path (default; preserves all prior behavior) and the new Share Group path, and a new "Acknowledgement Mode" property gates per-record vs. implicit acknowledgement when the share-group path is selected. - New KafkaShareConsumerService API contract plus Kafka4ShareConsumerService implementation wrapping org.apache.kafka.clients.consumer.ShareConsumer. - KafkaConnectionService gains a default getShareConsumerService() so third-party connection services remain ABI-compatible and only opt in when they support share groups. - Kafka3ConnectionService strips the classic-consumer properties rejected by ShareConsumerConfig.SHARE_GROUP_UNSUPPORTED_CONFIGS before constructing the share consumer. - ConsumeKafka.verify() exercises a share-group subscription and releases any sampled records back to the share group. - Bump the integration-test broker to apache/kafka:4.2.0 - Add unit tests for the share-consumer service (poll, explicit/implicit ack, commit, rollback, close, tombstone handling), the processor's share-group selection/verification/ack-mode wiring, and an integration test ConsumeKafkaShareGroupIT. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` - Pull request contains [commits signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) with a registered key indicating `Verified` status ### Pull Request Formatting - Pull Request based on current revision of the `main` branch - Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [ ] Build completed using `./mvnw clean install -P contrib-check` - [ ] JDK 21 - [ ] JDK 25 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
