Description

This patch adds support for deleting vertices along with their edges in the Nebula connector. A new feature flag, isDeleteExecutedWithEdges, is introduced to control this behavior. Additionally, tests are added to verify the new functionality while ensuring existing functionality remains unaffected.

How do you solve it?

1. NebulaVertices Class:

   • Added a new boolean field isDeleteExecutedWithEdges.
   • Modified the constructor to initialize this field.
   • Updated the getDeleteStatement method to use the appropriate delete template based on the isDeleteExecutedWithEdges flag.

2. VertexExecutionOptions Class:

   • Added the isDeleteExecutedWithEdges field.
   • Updated the constructor and builder pattern to include this new field.
   • Added a getter method for isDeleteExecutedWithEdges.

3. NebulaVertexBatchExecutor Class:

   • Passed the isDeleteExecutedWithEdges flag from VertexExecutionOptions to NebulaVertices.

4. NebulaConstant Class:

   • Added a new delete template DELETE_VERTEX_TEMPLATE_WITH_EDGE.

5. NebulaVerticesTest Class:

   • Added new test methods testGetDeleteStatementWithEdges and testGetDeleteStatementWithPolicyAndEdges to validate the new delete behavior.

Special notes for your reviewer

• Impact: This patch maintains backward compatibility by preserving the existing delete functionality. The new feature is controlled by the isDeleteExecutedWithEdges flag, ensuring that existing code paths remain unchanged unless explicitly modified to use the new feature.
• Design Document: The design follows the existing pattern of handling execution options and statements in the Nebula connector. The addition of a feature flag allows for flexible extension of delete behavior without intrusive changes.
• Testing: Comprehensive tests have been added to verify both the new and existing functionalities.
