Uninstalling Operator Libraries or Templates

If your business does not need the installed operator libraries or templates, or if you want to install a newer version, you can uninstall the libraries or templates to release the Stream Designing resource.

Note

Before uninstalling an operator library or template, ensure that no stream processing pipeline is still using the library or template.
