平台简介

基于kettle的数据流转平台,依托kettle的灵活性及丰富的组件生态,能灵活的实现各类复杂需求,本平台可以单纯作为一个kettle的调度平台,也可以作为一个灵活的数据流转平台,二者将是最完美的组合。

平台创建的作业最终都是生成kettle作业,有特殊需求可以在kettle中直接进行修改以满足特殊需求,灵活才是长期存活的基础。

其他非常规作业可以直接在kettle中设计后在本平台内进行统一调度管理。

本平台足够灵活,所谓有容乃大如是也,自身虽然已经足够强大,但仍具备不可比拟的包容性,任何外部优秀的东西都可以集成进来,因此本平台也是很完美的所有后台任务的统一管理平台。

kettle作为非常优秀的开源ETL工具得到了非常广泛的使用,一般的使用都是使用客户端操作管理,但问题是当投入生产环境使用时,动辄几百上千个job需要管理,这时在使用客户端管理已经很难完成了。我所知道的解决方案有用命令行的调用的,操作极其麻烦,难以维护,总之还是很难用啦,还有就是开发web端管理工具,kettle自带了一个web端管理工具,界面极其简陋不说,还很难用,基本无法投入生产环境使用,其他没留意到还有没有较好对众多job进行管理的工具。

基于以上情况和我多年的kettle定制开发与使用经验。我设计并开发了数据大师,在kettle的基础上,将常用的场景迁移到web端,使运维人员甚至普通客户都能实现常见需求,我的目标是web端能实现70%的需求,剩余一些特殊少见的需求则由数据人员在kettle中直接实现,然后统一在本平台调度管理。

本平台的具体优势请参考“平台特性”章节。

平台界面

作业管理

平台特性

  1. 【新】支持在一个调度中同时调度多个资源库的任务,也支持一个资源库的任务在多个调度节点上执行,同时支持在一个管理系统中同时管理多个调度节点。
  2. 新增支持设置作业启动时执行,支持cron定时,使定时设置更加灵活。
  3. 平台内支持创建:数据流转作业(暂时取消,设计有点复杂不太实用,目前有数据同步任务)、KM作业、javascript作业、shell作业、sql作业。
  4. 本平台能自动检测作业运行异常信息,便于平台运行状况跟踪,当作业量很大时,很难逐个作业查看运行情况。
  5. 本平台提供基础的运行日志,作为作业运行情况的回溯依据,便于事后问题排查。
  6. 平台提供设计好的数据流转日志功能,更接近业务层,用户可以根据需要使用。
  7. 平台提供转换管理,当前转换管理只提供查看、删除、查看转换图功能,将来根据需要提供导入功能。
  8. 数据库管理是管理kettle中配置的数据库信息,若是完全深入采用数据世界平台,那么这里的数据库都将采用jndi的形式关联使用数据世界中的数据载体管理,一处配置全平台通用,若是直接在kettle中配置的数据库,此处可以进行密码解密。

一些说明

  1. 本平台2015年投入使用,我们公司已经在多地部署使用,开源以来,外部也有大量用户,所有基础的作业调度功能已经稳定,新添加的功能基本属于锦上添花,有些小bug也难免,欢迎反馈,让我们一起让他变得更好。
  2. 本系统是基于数据库资源库设计的,暂时不考虑支持文件资源库,当前支持oracle和mysql。
  3. 关于kettle版本的问题,当前版本开发使用的是8.3版,之前版本采用5.4开发,目前建议使用8.3版

常见问题

作业添加

  1. 本平台是直接读取你数据库资源的v_job视图,这个视图包装了一下r_job表,你可以通过修改视图达到隐藏一些作业的目的。
  2. R_job是kettle资源库的系统表,只要你连接这个资源库设计的作业,都会记录在这个表中,所以你只需按照平常的习惯,连接与本平台配置的相同的资源库设计作业即可,因为读取的是同一张表,所以不需要额外的操作,直接就可以在本平台中看到你的作业并进行调度。
  3. 有外部作业需要添加到本平台,你只需直接使用kettle的Spoon工具,连接同一个资源库进行导入操作,这个数据人员都很熟悉。
  4. 我觉得没必要在页面支持作业导入功能,不知是否有这样的需求,这个暂时不开发。

查看转换

  1. 关于这个问题,我一直很困惑,为毛要直接查询运行转换,作业和转换可谓各司其职,我认为要运行转换就需要在其上包装一个作业,不管是否有其他流程依赖的需求。
  2. 当前新版本已经提供转换查看功能,支持直接在调度中将转换包装为作业进行运行。

注意事项

  1. 不要使用系统自带的记事本编辑配置文件,否则会导致系统无法正常读取你修改的配置文件,可以使用editpuls或notepad++。当出现奇葩问题时要想起这个提示。
  2. 相关文件最好不要存放在有空格或中文的目录下,避免不必要的麻烦。

后续计划

  1. 任务管理在设置定时时可能需要人为分散定时,考虑生成时间-运行任务数的分析图辅助进行分散定时。
  2. 权限管理,不同用户看到自己的作业,管理员看所有作业。
  3. 分布式、集群支持,考虑增加容灾机制。
  4. 根据日志加入一些统计功能

框架简介

本系统全面参数化,采用类似前端框架的参数组织形式,使系统足够灵活,可配置性极强。

技术架构

本项目采用的技术选型如下:

  1. 数据库:暂时oralce、mysql,可以很快实现支持各类数据库。
  2. 后端:springboot2+beetlsql+redis
  3. 前端:vue3+vxe-table+element

框架特点

  1. 技术选型:前后端采用当前最流行且较新版本的技术方案:springboot2、beetlsql、fastjson、druid、vue3、vxe-table、element-plus、各种数据库
  2. DAO工具:数据库层采用了beetlSql,国产优秀DAO层工具,我认为比hibernate和mybatis更好,hibernate封装过深,大部分人使用多年仍然只会皮毛,mybatis的xml配置sql也是很不友好的,而beetlSql同时兼具此二者优点,代码量不大,代码可读性强,模板语法类似javascript,采用markdown形式组织SQL,简单易学,遇到问题也可以直接下载源码进行内部细节了解及改造,我也向官方推送过代码,这是真正掌握在自己手上的优秀DAO层工具。
  3. 多数据源支持:灵活动态的配置数据源,一处配置多处使用,代码中可以非常方便的切换数据源,kettle中也可以直接使用该数据源配置,本系统封装Db工具,实现常用数据库操作的简化,方便的切换数据库方式,开发体验飞起来。
  4. 运行简单:项目依赖服务极少,经过反复思考,目前项目主要依赖redis(可选择)和数据库(目前已经适配mysql和oracle),使项目更简单,可以快速简单运行部署。
  5. 全面参数化:本系统全面参数化,采用类似前端框架的参数组织形式,使系统足够灵活,可配置性极强,并且提供完整的参数文档。
  6. 接口统一:平台所有接口支持pc端、app端、第三方方便调用,对外接入及共享数据无需开发代码,通过简单的配置即可实现。
  7. 日志封装:采用logback日志框架,并集成转换框架可以兼容log4j和common-longging等日志框架,从而实现了日志的统一,同时自己实现日志记录器,支持将系统所有异常日志记录到数据库中,便于后续系统维护预警,同时我进行了简单的logbak日志封装,开发中可以方便的使用日志记录,且不会影响日志中的类命名及堆栈信息。
  8. 面向对象:面向对象的系统架构思路,万物皆对象,计划支持各类支持jdbc的数据库、文件、ftp等数据形式。
  9. 统一字典:统一的字典服务,汇集全平台所有字典并提供统一服务,可以非常灵活的集成各处数据进行字典服务,具体请参考开发规范中字典管理章节。
  10. 文件服务:统一的文件服务,全平台统一文件服务,支持文件上传到本地文件系统、ftp、hdfs、数据库等数据载体中,可以清晰的查询下载到平台所有上传的文件。
  11. 统一配置:极简的实现配置分布式管理,支持配置继承,没有任何依赖。
  12. 统一验证转换:本系统实现统一的验证、转换机制,可以对每个请求的参数进行校验、转换配置。
  13. 精细系统日志:系统操作日志记录精准,除了常规的请求路径、ip、操作人等信息外,本系统日志参数代码自动翻译为中文,记录日志入参、返回结果、耗时记录等,便于排查系统性能点进行精准优化。
  14. 不一样的权限体系:简洁强大的权限控制系统,本框架角色可以有子角色,父角色默认包含子角色权限,可以对未登陆的用户授权,可以对所有登陆的用户授权,支持按钮操作级授权等。
  15. 低代码:本系统已经实现通用的增删改查,并提供通用的数据模板下载、数据批量上传、数据导出、列表编辑、记录复制等特色功能,后续还可根据需要自行定义各系统通用方法,大部分需求不需要开发代码即可通过配置实现,本系统也不生成代码,配置会缓存在内存中,性能不受影响,配置修改实时生效,同时还能非常灵活的满足任何特殊需求,这是与目前市面上绝大部分低代码框架的最大区别。
  16. 插入更新:本系统支持按业务字段进行去重,在新增和批量上传时可以按业务字段进行查重后自动选择插入和更新。
  17. 国际化支持:集成国际化支持,可以便捷的开发国际化系统。
  18. 定时任务:本系统集成xxl-job作为定时任务管理机制,可以方便的进行定时任务的开发及管理。
  19. 智能交换:本系统提供一个智能交换系统,能方便的配置实现本地文件、ftp、kafka等数据载体间的数据近实时同步,从而简单快捷实现高效的跨网数据交换等复杂需求。

GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.
