CloverETL 4.1M1

The next step on the journey of steady improvement of CloverETL.

Six months after releasing the successful CloverETL 4.0, which brought innovative features like subgraphs and metadata propagation, we’re releasing another update. CloverETL 4.1 milestone release is now available for download.

Based on feedback from our customers coupled with our own experience, we made a lot of adjustments to subgraphs making them even easier to use. We’ve introduced a concept called the “Generic Java Component”, which allows you to program your own components using Java. Together with subgraphs, this feature makes CloverETL one of the most versatile data integration tools on the market. We’ve added native support for HP Vertica and Amazon Web Services. And many other features and improvements.
We’ve also made significant changes to the user interface, so learning and working with CloverETL is now much simpler.
