运行模式
standalone模式
SDK
数据推送与推荐接口交互client，目前仅支持java版本
rec-server
推荐系统在线服务，整合实时数据链路、运营操作以及召回+排序链路，完成整套推荐系统在线服务功能串通
rec-algorithm
推荐算法模块，基于pandas实现，故而目前仅支持单机环境：包含i2i,word2vec,hot以及new四种召回算法
recall-engine
推荐召回引擎，包括两部分
- redis：用户i2i,hot,new以及曝光过滤等
- elasticsearch：用于向量召回以及文本检索
example
顾名思义，为了使开发者更容易的了解整套链路的工作流程而准备的辅助模块
cluster模式
主要是rec-algorithm以及实时链路部分会进行集群版本的扩充，挖个坑先... 先将standalone版本放出来试试水，尝试搜集下需求和建议，当然如果能一起参与开发就更好了，说实话一个人搞还是蛮累的...
