Talend Studio includes powerful testing, debugging and tuning features that allow the real-time tracking of data flowing through the whole transformation processes, including execution statistics and an advanced trace mode.
Talend Studio also streamlines development by providing visibility into live statistics of message flow activity within a specific messaging route. You can simulate messaging routes from within Eclipse and observe the execution flow, with statistics on each aspect of the route that is executed for each message. This enables rapid prototyping for developers, dramatically reducing development and testing cycles.
And, of course, all code generated by Talend Studio, regardless of the target language, is always visible and accessible from the design environment.
