[Feature Summary] Enhancement and optimization OLTP algorithm & api

[DanGuge]

Feature Description (功能描述)

Background

HugeGraph provides interfaces for querying through RESTful APIs. However, in the current RESTful API corresponding to the OLTP algorithms, both the algorithms and functionalities are not yet fully complete and require further expansion. There is also room for optimization in the execution of the algorithm. Therefore, in this feature implementation, we have set the following objectives:

• Provide more comprehensive query result information and details about algorithm execution
• Enhance algorithm execution efficiency through techniques such as pruning and parallelization

In the existing HugeGraph framework, the OLTP algorithm corresponds to the following interfaces, all of which will be subject to modification:

Tasks

• Enhance all OLTP algorithm APIs by adding statistical information, including the number of traversed vertices, edges, and execution time feat(api&core): in oltp apis, add statistics info and support full info about vertices and edges #2262
• Enable support for returning partial/complete information of vertices and edges in all OLTP algorithm APIs feat(api&core): in oltp apis, add statistics info and support full info about vertices and edges #2262
• Provide support for filtering vertex and edge properties in OLTP algorithm APIs, reducing unnecessary graph searches through pruning code link
• Integrate DFS query mode into the Kout algorithm code link
• Implement support for batch processing and concurrent execution using multiple threads
• Add the related doc in website
