Description

1. Description
   HugeGraph is an easy-to-use, efficient, and general-purpose open-source graph database system.
   To facilitate users in efficiently writing data from various data sources (like MySQL, Kafka, ClickHouse, etc.) into HugeGraph, we propose adding a new V2 connector for SeaTunnel: connector-HugeGraph.

2. Task Proposal
   The implementation of the HugeGraphSink connector should support the following core features:

   Connection Configuration: Support configuration for the HugeGraph Server URL, graph name, and authentication details.
   Write Vertices (Vertex): Support mapping and writing SeaTunnelRow data as Vertices in HugeGraph, including configuring the label, ID strategy (e.g., PRIMARY_KEY, CUSTOMIZE), and properties.
   Write Edges (Edge): Support mapping and writing SeaTunnelRow data as Edges in HugeGraph, including configuring the label, source vertex ID, target vertex ID, and properties.
   Batch Writing: Support efficient batch writes (Batch Write) to improve throughput.
