需要这个完整离线数仓项目的源码和流程PPT可以私信我，可以帮助解决项目中遇到的问题，做完项目可以让你对数仓有更加清晰的认识

项目流程：

配置文件

kafka server.properties

hive : hvie-site.xml

启动mysql 的binlog日志

修改maxwell配置文件监听mysql的数据同步到kafka

配置flume-ng文件采集kafka—incdb 主题消费到的数据并上传至hdfs

flume-config

agent.sources = source_from_kafka 
# channels alias 
agent.channels = mem_channel

agent.sinks = hdfs_sink 
# define kafka source 
agent.sources.source_from_kafka.type = org.apache.flume.source.kafka.KafkaSource agent.sources.source_from_kafka.channels = mem_channel agent.sources.source_from_kafka.batchSize = 5000

agent.sinks.hdfs_sink.hdfs.threadsPoolSize = 30 agent.sinks.hdfs_sink.hdfs.fileType=DataStream agent.sinks.hdfs_sink.hdfs.writeFormat=Text 
# define channel from kafka source to hdfs sink 
agent.channels.mem_channel.type = memory 
# channel store size 
agent.channels.mem_channel.capacity = 100000 
# transaction size 
agent.channels.mem_channel.transactionCapacity = 10000

开启maxwell监听：
