> Key: CAMEL-11484
> URL: https://issues.apache.org/jira/browse/CAMEL-11484
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Fix For: 2.20.0
>
>
> If you use a simple expression in a Camel route that has a simple token, then
> it's re-created per exchange during routing. The expression by itself can be
> cached and reused, which avoids using the simple parser over and over again.
