CloverETL 4.0

Helping Developers Empower Business

Watch CloverETL 4.0 Overview Video

CloverETL 4.0 introduces subgraphs, a powerful way of creating user-defined components that let you hide complexity and design data transformations on a much higher level, using business components rather than low-level data operations. Also, the new features that support subgraphs are very useful on their own – automatic metadata propagation reduces the need to manage metadata in transformations, while the execution view panel gives you easier access to debug information for faster development.

  • Major New Feature


Reduce complexity, create business-level components, share your expertise. Create new components without programming. Wrap complex functionality into a simple interface.

Create new data sources and targets

Embed connections, metadata and other properties into subgraphs and share them with others.

Focus on business logic

Create a library of your business logic components, rather than low-level data processing functions.

Reduce complexity

Wrap logical parts of large transformations together into steps that you can easily drill into.

Share your expertise

Solve hard problems and share the solution with others. Everyone can contribute.

  • New Feature

Automatic Metadata Propagation

Metadata are now automatically
assigned to edges when possible.

Save time and effort

No need to assign metadata to every edge – they are determined based on the component and its surroundings.

Reuse transformations

Changes automatically propagate through complex transformations, making them easier to reuse.

Distribute with subgraphs

Metadata embedded into subgraphs are readily available in upstream transformations, with no linking needed.

  • New Feature

Execution View Panel

View execution history and visually access debugging data for subgraphs and jobflows.

Real-time tracking

Watch data in real time as it flows through your transformation or jobflow.

Access stored debug data

Just double-click any layer of subgraphs or nested jobflow, and inspect collected debug data.

Troubleshoot finished runs

Connect to jobs executed by the Server and visually inspect what data flowed through successfully, in order to find potential problem areas.

  • New Feature

Tableau TDE Support

Create Tableau Extract files (TDE), directly enabling rapid data preparation and development.
