When set, it overrides the `max.poll.records` value of the Kafka Connection Service for that Processor. When not set, the Connection Service value applies, so existing flows are unchanged. | Property | Default | Description | |---|---|---| | Max Poll Records | none | Maximum number of records returned from a single poll of Kafka. Overrides the Max Poll Records property of the Kafka Connection Service for this Processor. | Changes: - `PollingContext` carries an optional Max Poll Records value through new constructors. The existing constructors are unchanged. - `ConsumeKafka` passes the property value in `PollingContext`. - `Kafka3ConnectionService.getConsumerService` applies the value after the service consumer properties. - Added `ConsumeKafkaTest` cases for validation and for the value passed in `PollingContext`, and a `Kafka3ConnectionServiceBaseIT` case where the service sets 10 and the `PollingContext` sets 2, verifying that a single poll returns 2 records. # 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 - [x] Build completed using `./mvnw clean install -P contrib-check` (for `nifi-extension-bundles/nifi-kafka-bundle`) - [x] 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
