DataService-Framework

项目介绍

基于大数据平台的数据处理服务框架。
结合大数据项目实际使用场景,提取出的一些通用的功能,形成大数据平台数据处理框架。
目前主要实现的功能有:
1、参数信息配置模块,可实现采用数据库进行配置和Properties文件进行配置
2、集成Kafka,实现了Kafka的生产者和消费者相关的功能
3、集成MongoDB,实现了MongoDB的数据读取、写入等,实现了SparkSQL通过DataFrame与MongoDB的数据进行交互,并且实现了分页读取、流式读取等特殊读取方式
4、集成Redis,实现了Redis的读取、写入等,实现了SparkSQL通过DataFrame与Redis的数据进行交互
5、SparkStreaming流式处理Kafka、MongoDB的数据
6、手动记录Kafka的偏移量,实现了基于数据库进行记录和基于Zookeeper进行记录
7、集成了规则引擎,客户标签、客户画像等功能可基于规则引擎进行实现

软件架构

软件结构如下:

DataService-Framework      项目根目录
├── commons             公共功能模块,提供配置文件读取、数据库连接、日志打印、工具类等公共功能,以供其他模块调用。  
├── examples            样例模块,提供各个功能点的样例代码。  
├── kafka-clients       KafkaClients相关功能,比如生产者、消费者等。
├── kafka-streams       主题数据过滤模块,Kafka自带的流处理功能,业务系统记录的日志如果包含了大量的:程序异常日志、数据库操作日志、调试日志等日志信息,而采集的数据只需要日志文件中的特定数据的日志记录,那么对于我们采集到的日志来说,可能会有90%以上的日志都是垃圾数据,但是Flume组件没有提供日志过滤功能,而Spark程序又不应该消费这些数据。这时就需要提供一个中间层,将Flume采集到的Topic1的日志中满足条件的数据筛选出来放到Topic2中,Spark程序只需要消费Topic2的数据即可,过滤条件按照正则表达式进行配置。这样Spark消费Topic2的数据都是我们需要的数据,并且我们可以及时的清理掉Topic1的数据以释放空间。
├── rule-engine         规则引擎功能。
├── spark-sql           SparkSQL相关功能,扩展了Dataset/DataFrame的方法,集成Redis数据的读写、MongoDB数据的读写。  
├── spark-streaming     SparkStreaming实时数据处理模块,通过SparkStreaming程序,准实时消费Kafka中的数据,流式方式处理MongoDB中的数据。
└── third-party         第三方源码
      ├── hammurabi     Scala规则引擎
      ├── mongodb       Spark操作MongoDB
      └── redislabs     Spark操作Redis

功能扩展

目前,软件实现了Flume数据采集、Kafka主题数据过滤、SparkStreaming实时数据处理。但是SparkStreaming的数据处理只实现了代码值标准化等基础功能。并且,目前默认支持的采集日志格式只有两种:分隔符分隔字段的数据、JSON格式的数据。
功能扩展可以从两个方面进行:

  1. SparkStreaming程序扩展,可以继续增加程序处理功能,完成更复杂的数据处理,比如:指标加工、客户行为分析、客户画像等
  2. 日志格式扩展,目前只开发了支持两种类型的日志格式,可以自定义类实现com.service.data.spark.streaming.process.TopicValueProcess接口,以实现其他格式的日志内容的解析。自定义实现类后,需要在spark-kafka模块的resources/META-INF/services/com.service.data.spark.streaming.process.TopicValueProcess文件中添加一行记录类名称,并且在使用过程中将其配置到数据库中即可。
