Talend Data Integration is one of many Talend products that helps us simplify ETL processes that were previously scattered among various shell scripts and stored procedures. Once the basics and components are understood, you can create almost any extract or load script imaginable by simply dragging components over from the tool palette and wiring them together. Processes can be run from within the GUI or compiled to shell scripts for hooking into other processes. The tool is widely used, so it's easy to find support online. This includes official support forums and a knowledge base hosted by Talend. Review collected by and hosted on G2.com.
The interface can be deceiving on first glance. You really need to understand each of the components before you know its inputs and outputs fully. In fact, I occasionally had a problems with the interface not showing up completely. That was in an older version and may have been fixed now. It can be confusing understanding how data will be mapped between components. Our projects end up being a Java "black-box" requiring Talend to modify, even when compiled to run from the command line. That wouldn't be a problem if our entire process was contained within Talend, and online unofficial and official support channels were helpful in overcoming such issues.

After building your solution, the implantation part (taking it from workspace to production) is not as clear as all other parts. And took me several times doing it before I felt even the remotely comfortable. Review collected by and hosted on G2.com.
I think the best feature of Talend is the free version. This version can meet 80% of data integration activities in most companies, and some companies may be sufficient. There are many great features for free. The interface is simple and easy to understand and work. Review collected by and hosted on G2.com.
The main deficiency in my opinion is that there is still a need for coding in Java for some more specific work, which restricts a little the public who can make the best use of the tool. Review collected by and hosted on G2.com.
