<!-- SPDX-License-Identifier: Apache-2.0 --> # Summary [NIFI-16574](https://issues.apache.org/jira/browse/NIFI-16574) This adds the NiFi API changes for draining a Process Group, as proposed in [NIP-51](https://issues.apache.org/jira/browse/NIP-51). - Adds the `@OnDrainInitiated` and `@OnDrainCompleted` lifecycle annotations. Processors and Controller Services can use them to process their data more aggressively while their Process Group is being drained. For example, MergeContent can use a short Max Bin Age so that bins don't wait a long time for more data that will never arrive. - Adds `beginDrain()` and `endDrain()` default methods to `ProcessGroupLifecycle`. - Updates `AbstractConnector.drainFlowFiles` to use those methods, so that a Connector drains its flow the same way as a Process Group. The protected helper methods in `AbstractConnector` are unchanged. All changes are additive and backward compatible. The framework and UI work is tracked separately under [NIFI-16573](https://issues.apache.org/jira/browse/NIFI-16573). # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [x] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [x] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [x] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [x] Pull Request based on current revision of the `main` branch - [x] Pull Request refers to a feature branch with one commit containing changes -- This is an automated message from the Apache Git Service.
