基于规则的转换组件(RBT)

datax 注意力大部分是reader/writer, datax的设计核心在于星型结构，即，reader/writer可以随意撤换，中间exchanger作适配，Transfomer应该是最重要的角色，但datax本身Transfomer比较简单，本组使用xql/规则实现Transfomer构建，适配reader/writer，目前以图库为writer，但可作为探索，实现低代码datax

Start by reviewing DataX's existing reader, writer, exchanger, and Transformer design, then read the linked RBT design article and the diagrams in the issue. The scope is complete when a rule-based Transformer design is defined and its compatibility with interchangeable readers and writers is demonstrated, including the described graph-database writer scenario.
