Finding a right Open Source ETL tool is dificult. I have done some searching on the internet on different websites and blogs and I have listed out the following Open Source ETL tools. Different Open Source ETL Tools was studied based on License requirements, history, Open source nature and support of the product. I have singled out four tools namely Talend, CloverETL, Pentaho and SpagoBI. The fundamental overview of these tools are as under:
Talend – It is a startup of French origin that has positioned itself as a pure play of open source data integration and now offers its product - Open Studio. For vendors wishing to embed Open Studio capabilities in their products, Talend has an OEM license agreement. That is what JasperSoft has done, thus creating an open source BI stack to compete with Pentaho's Kettle. Talend is a commercial open source vendor which generates profit from support, training and consulting services. What Open Studio offers is a user-friendly graphical modeling environment as it provides traditional approach for performance management as well as a pushdown optimization (architectural approach). The latter allows users to bypass the actual cost of dedicated hardware to support an ETL engine and enables users to leverage spare capacity of the server within both the source and target environments to power the transformations.

CloverETL – Clover ETL is a data transformation and data integration tool (ETL) distributed as a Commercial Open Source software. As the Clover ETL framework is Java based, it is independent and resource- efficient. CloverETL is used to cleanse, standardize, transform and distribute data to applications, database and warehouses. Clover ETL has been used not only on the most wide spread Windows platform but also on Linux, HP-UX, AIX, AS/400, Solaris and OSX. It can be both used on low-cost PC as on high- end multi processors servers. CloverETL is easy to buy. No complex subscriptions or confusing service tail. Just the software license and maintenance, pure and simple. License is priced by CPU and in easy-to-use packages. Allows you to grow and upgrade to higher levels within the year. CLoverETL Website
Pentaho - If embedding in a commercial application, obliged to make your application available under the GPL open source license, For Enterprise Edition No up-front license costs , Annual subscriptions available for product support and training . Pentaho offers a basic reporting solution but also a more advanced Pentaho BI (including OLAP analysis, dashboards and data mining). To benefit from additional BI functions, a Gold or Platinum subscription can be purchased. The subscription also enables access to extended service levels that are not available for open source software. The Pentaho BI platform runs on Windows, Linux and Mac OS, and is based on server-side Java, Ajax, and Eclipse environment. Pentaho Community Edition can be used for Commercial purpose.

SpagoBI - Is a BI platform popular in Europe and owned by Engineering Ingegneria Informatica (EII) based in Italy. SpagoBI offers an alternative approach of their consultants building and implementing custom solutions for their key customers. EII has released a single version of SpagoBI, which is available on OW2 Consortium Web site (www.ow2.org) since 2004 for public use.
