With Sling Pipes it's very easy to update the AEM content. It is a tool for executing CURD operations over resources in AEM repository. Hope this will be helpful.
Plumber is OSGi service and it has newPipe method in which we need to pass resourceResolver. After that we can call several pipes or methods to achieve our objective. Some of them are-
echo(path) - to retrieve the root resource of the path.
write(config) - to write/update properties of a resource.
run() - to execute the code.
Use case: To update property of a node using Sling Pipe OSGi service.
