[Summary] Serialization Optimization/Performance Optimization Task

[msgui]

Task Summary - HugeGraph Serialization Optimization/Performance Optimization(任务汇总 - HugeGraph 序列化优化/性能优化)

Task Description (任务描述):

This task focuses on optimizing the serialization process and improving the overall performance of HugeGraph. It involves various strategies and techniques to enhance the efficiency and effectiveness of serialization operations.(这个任务的重点是优化HugeGraph的序列化过程，提高系统的整体性能。它涉及到多种策略和技术，以增强序列化操作的效率和效果。)

Tasks to be Completed (需要完成的任务) :

Update in 2023.07.13

• 1.Support constant enumeration encoding for frequently occurring property values.
  (支持对高频属性值进行常量枚举编码)

• 2.Introduce lazy deserialization for BackendProps by wrapping the original bytes.
  (通过将原始字节包裹起来，实现按需延迟反序列化类BackendProps)

• 3.Replace individual byte arrays with byte buffers to reduce fragmentation during serialization.
  (在序列化过程中，将各个字节数组替换为字节缓冲区，减少碎片)

• 4.Optimize off-heap memory usage for gremlin dedup/emit steps.
  (针对gremlin dedup/emit等步骤，优化堆外内存的使用)

• 5.Fine-tune the caching structure for adjacency edges, such as using vertex Id as the key to improve cache hit rate.
  (优化邻接边的缓存结构，例如使用顶点Id作为键，提高缓存命中率)

• 6.Improve the efficiency of adjacency edge queries with target point Id conditions.
  (优化带有目标点Id条件的邻接边查询的效率) @msgui (done feat: optimising adjacency edge queries #2242)

• 7.Optimize for adjacency edge query: skip source-vertex if edge-label does not link source-vertex's label.
  (如果顶点类型不具有该类型的边，通过直接返回空结果来优化根据顶点查找边的过程) @Z-HUANT (done feat(api): optimize adjacent-edges query #2408)

• 8. Replace the current serialization framework with the high-performance serialization framework Fury. （将当前序列化框架替换成高性能序列化框架Fury）
