System Requirements
- Linux
- JDK(1.8以上,推荐1.8)
- Python(推荐Python2.6.X)
- Apache Maven 3.x (Compile DataX)
Quick Start
工具部署
方法一、直接下载DataX工具包:DataX下载地址
下载后解压至本地某个目录,进入bin目录,即可运行同步作业:
$ cd {YOUR_DATAX_HOME}/bin $ python datax.py {YOUR_JOB.json}
自检脚本:
python {YOUR_DATAX_HOME}/bin/datax.py {YOUR_DATAX_HOME}/job/job.json方法二、下载DataX源码,自己编译:DataX源码
(1)、下载DataX源码:
$ git clone git@github.com:alibaba/DataX.git
(2)、通过maven打包:
$ cd {DataX_source_code_home} $ mvn -U clean package assembly:assembly -Dmaven.test.skip=true
打包成功,日志显示如下:
[INFO] BUILD SUCCESS [INFO] ----------------------------------------------------------------- [INFO] Total time: 08:12 min [INFO] Finished at: 2015-12-13T16:26:48+08:00 [INFO] Final Memory: 133M/960M [INFO] -----------------------------------------------------------------
打包成功后的DataX包位于 {DataX_source_code_home}/target/datax/datax/ ,结构如下:
$ cd {DataX_source_code_home} $ ls ./target/datax/datax/ bin conf job lib log log_perf plugin script tmp
配置示例:从stream读取数据并打印到控制台
第一步、创建创业的配置文件(json格式)
可以通过命令查看配置模板: python datax.py -r {YOUR_READER} -w {YOUR_WRITER}
$ cd {YOUR_DATAX_HOME}/bin $ python datax.py -r streamreader -w streamwriter DataX (UNKNOWN_DATAX_VERSION), From Alibaba ! Copyright (C) 2010-2015, Alibaba Group. All Rights Reserved. Please refer to the streamreader document: https://github.com/alibaba/DataX/blob/master/streamreader/doc/streamreader.md Please refer to the streamwriter document: https://github.com/alibaba/DataX/blob/master/streamwriter/doc/streamwriter.md Please save the following configuration as a json file and use python {DATAX_HOME}/bin/datax.py {JSON_FILE_NAME}.json to run the job. { "job": { "content": [ { "reader": { "name": "streamreader", "parameter": { "column": [], "sliceRecordCount": "" } }, "writer": { "name": "streamwriter", "parameter": { "encoding": "", "print": true } } } ], "setting": { "speed": { "channel": "" } } } }
根据模板配置json如下:
#stream2stream.json { "job": { "content": [ { "reader": { "name": "streamreader", "parameter": { "sliceRecordCount": 10, "column": [ { "type": "long", "value": "10" }, { "type": "string", "value": "hello,你好,世界-DataX" } ] } }, "writer": { "name": "streamwriter", "parameter": { "encoding": "UTF-8", "print": true } } } ], "setting": { "speed": { "channel": 5 } } } }
第二步:启动DataX
$ cd {YOUR_DATAX_DIR_BIN} $ python datax.py ./stream2stream.json
同步结束,显示日志如下:
... 2015-12-17 11:20:25.263 [job-0] INFO JobContainer - 任务启动时刻 : 2015-12-17 11:20:15 任务结束时刻 : 2015-12-17 11:20:25 任务总计耗时 : 10s 任务平均流量 : 205B/s 记录写入速度 : 5rec/s 读出记录总数 : 50 读写失败总数 : 0
