Re: [HEADS UP] - Introducing variables to Camel 4.4
Ok make sense, thanks for clarification Claus.
With user variables separated from internal exchange properties, I wonder
if properties become kind of read-only from user perspective.
And yes, the naming is even harder in this area with context global
options, exchange properties, component options, endpoint options... :)

exchange properties is a mixed bag of internal stuff and yes users can also
store their own stuff there.
But then you end up with user stuff and internal camel stuff. Also exchange
properties are private per exchange only.
Variables = 100% end user.
And you can have different scopes / repositories so you can share
variables, or persist them or whatever.
Also a variable is a more common concept for users as it's something every
programming language has.
Exchange properties can be mistaken for those "properties" you configure on
endpoints, components, and in application.properties, and when using
property placeholders {{xxx}}.
In fact they were called properties in Camel 1.x/2.x and renamed to
exchange properties to better say that these are properties on an exchange,
and not any of

Re: [HEADS UP] - Introducing variables to Camel 4.4
Hi Claus, Looks interesting. New year, new idea :) I wonder what is the difference between exchange property and variable. Don't they have the same scope and mutability ?

[HEADS UP] - Introducing variables to Camel 4.4
Hi JIRA https://issues.apache.org/jira/projects/CAMEL/issues/CAMEL-19749 We are working on adding support for variables to Camel. See more in the docs at https://github.com/apache/camel/blob/main/docs/user-manual/modules/ROOT/pages/variables.adoc And examples for Spring Boot and Main / JBang https://github.com/apache/camel-spring-boot-examples/tree/main/variables https://github.com/apache/camel-kamelets-examples/tree/main/jbang/variables There is more work coming, but this is the initial and basics of variables. -- Claus Ibsen - @davsclaus Camel in Action 2: https://www.manning.com/ibsen2
