Agenda

Toolset for performing extract, load & transform operations on content within JCR repository using reusable code blocks called pipes.

Let’s say business requests us to enable override title & description on all game pages
OR due to a component update we had to remove/modify a property in all occurrences of that component’s node
OR create a CSV of pages which are using image components

Sling pipes is not included with vanilla AEM installation, following bundles have be to installed:
- Sling Pipes - https://mvnrepository.com/artifact/org.apache.sling/org.apache.sling.pipes
- Sling Query - https://mvnrepository.com/artifact/org.apache.sling/org.apache.sling.query
Create the node hierarchy: /system/sling/permissions/pipes/exec
Note: For updating which groups can run sling pipes on a AEM instance, update Apache Sling Pipes : Plumber configuration

Sling resource tree traversal tool inspired by the jQuery JavaScript API, providing convenient way to traverse resource tree.
Note: Sling query is not a replacement of JCR query, its just a tool for making traversal of resources easier, more details can be found here: sling query

Reader Pipes – only used for reading resources, usually used with writer & logical pipes
Writer Pipes – used for performing write, update, move or remove operations in JCR repository, can even create packages
Logical Pipes - can be used for referring to other pipes, chaining them or using their results in a general way
