Pull Request Overview
This PR introduces deployment mode switching for the QueryNode component by adding a new DeployMode field and corresponding reconciliation logic to enable switching between single (OneDeployMode) and dual (TwoDeployMode) deployment modes. Key changes include modifications to the controller logic for deployment mode reconciliation, new methods for switching deployment modes, and extensive test cases covering various operational scenarios.

- [nitpick] Consider extracting the deployment name format into a shared constant for consistency and easier maintenance across both test and production code.
currentDeployName := fmt.Sprintf("%s-%s-0", QueryNode.Name, mc.Name)

- [nitpick] Extract the deployment naming pattern into a constant to ensure consistent formatting and reduce the risk of mismatches when referenced elsewhere.
currentDeployName := fmt.Sprintf("%s-%s-0", c.component.Name, mc.Name)

@haorenfsa Thanks for the quick response and for taking the time to review，No rush at all, please handle your other tasks first. This is my first code-related PR to Milvus, so if I’ve made any mistakes (like the extra commits from #291), I really appreciate your patience and guidance. Thanks again for your support! |

You also need to run make generate-all after you changed the CRD.

you may move the code inside to a function named like ReconcileQueryNode() to avoid making Reconcile() too long.

I think the Above Update() is redundant. You can delete it directly, the pods will also be scaled down.

@haorenfsa Thank you for your guidance! I will make the suggested changes as soon as possible. I appreciate your time and effort in reviewing this PR. |

Please review the code, especially the modifications to the test cases, to ensure they meet the standards. If everything is in order, I will proceed with the HPA-related deployment mode switching functionality in the next PR after this one is merged. Thank you!
