Global elements in Mule allow you to configure elements once and then reference them multiple times from flows, rather than repeatedly writing the same code. They provide flexibility by allowing elements to use a global element's configuration exactly or with modifications, and they are reusable by configuring an element once and sharing it. Global elements also offer efficiency by changing a configuration in one place and having it apply to all elements that reference it.

1. Mule Global elements

2. Global Elements
• In Mule, a Global Element is one that you
configure once, then reference many times
from elements within multiple flows. Rather
than repeatedly writing the same code to
apply the same configuration to multiple
elements in flows, you can create one global
element that details your configurations or
transport details.

3. How to create global element. If you want to add global
element to DB. Refere example below

4. Click on MySQL DB then ok

5. We can specify the credentials here or
through Spring beans

6. This global end point we can use entire
application or project

7. Configuration XML here

8. • Global elements provide flexibility. An element can apply a global
element’s configuration exactly as defined, or can enhance the
global configuration with modifications.
• Global elements are reusable. You can configure a global element
just once, then share that configuration among building blocks of
the same type. This is particularly useful when you have to define
the connection details and login credentials for an external source,
such as a SaaS application or database.
• Global elements offer efficiency.
Rather than changing the same configuration multiple times within
many building blocks, you can change a configuration once, in the
“master”, and Studio applies the changes to all that reference it.
