Customer Portal

Building on the foundation of CloverETL 4.0, we are enhancing several existing features and adding couple of a new ones. Based largely on feedback from our customers, this release is aimed to improve development of data integration jobs.

New features in 4.1

Optional Ports

Expanding the concept of subgraphs. It allows you to create subgraphs, where users don't need to provide all inputs or outputs.

Better support for AWS and HP Vertica

Adding native support for S3 protocol and better directory management in AWS. New connector for HP Vertica and improved field types support.

Generic Java components

Allows to turn Java code into CloverETL component. Be it custom readers, writers or any transformations.

Dynamically disabled components

Adding new ways to disable components. It is now possible to turn component into trash for debugging purposes, or conditionally disable component based on the connected edges or graph parameters.

Improvement to UI and UX

Updated tooltips, keyboard shortcuts, turning debuging on and off on all edges at once and many more improvements to help you develop your data integration jobs.
