Extensions (original) (raw)
The Cascading ecosystem is filled with support for a variety of programming languages, data sources, serializers and tools that extend the functionality of Cascading applications.
These extensions are available for use with Cascading and are contributed code from the Cascading community. Many new projects are actively available through Cascading GitHub and the Conjars Maven jar repository.
Note: Most projects are hosted on GitHub and may have multiple branches and forks as users enrich the original projects. Many are also under active development.
