#Blazer/数据传播者
Blazer意为**传播者**，主要实现不同数据库之间的数据同步，导出数据库表结构创建语句。
1、导出数据库表数据到txt文件或者excel
1. 导出数据库表数据到txt/CSV文件（多线程）或者excel(.xlsx/.xls)；
2、把txt文件或者excel中的数据导入到数据库表
2. 把txt文件或者excel中的数据导入到数据库表，支持基于javascript脚本对数据的处理；
3、翻译特定的数据ddl成其他数据库的语法，方便数据迁移
3. 翻译特定的数据库表结构ddl成其他数据库的语法，方便数据迁移；
4、数据库之间的数据同步
\ No newline at end of file
4. 数据库之间的数据同步；
5. 目前支持数据有mysql/MariaDB,Greenplum,Oracle,DB2,PostgreSQL;
------------
项目基于Java Spring Framework框架，简化了系统的配置，引入"管道"（PipeLine）的概念，一个管道包含多个任务，任务可以是数据同步、导入、导出或者表结构的导出。
在不同的XML中引入不同管道任务，实现不同的功能，其中pipeLine.xml描述管道的功能，需要根据需求进行定义，可以基于以下的命令内容copy出不同脚本功能。
