Andrea Cosentino updated CAMEL-13119:
-------------------------------------
Fix Version/s: 3.0.0-M1
> Create Cache Policy for routes
> ------------------------------
>
> Key: CAMEL-13119
> URL: https://issues.apache.org/jira/browse/CAMEL-13119
> Project: Camel
> Issue Type: New Feature
> Components: camel-jcache
> Reporter: Balazs Szeti
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 3.0.0, 3.0.0-M1
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Let's write a Policy for camel routes that can cache the "result" of a route
> and execute the route next time only if nothing is found in the cache.
>
> Related to cache DSL idea, but without DSL change:
> https://issues.apache.org/jira/browse/CAMEL-11114
>
> In the first draft the CachePolicy would cache the Message Body by a key
> calculated via an Expression.
> Interface:
> * cachePolicy.setCacheManager( cacheManager ) - set the CacheManager. If not
> set, try lookup automatically.
> * cachePolicy.setCacheName ( name ) - Will use this cache from the
> CacheManager. If not set, we can use the route id by default.
> * cachePolicy.setKeyExpression( expression ) - Camel expression that is
> evaluated on the Exchange to determine the cache key. If it's found in the
> cache, the route is not executed and the cached value is set as Body.
> Otherwise the Message Body is added to the cache after the route with this
> key.
>
> An earlier related implementation:
> [https://gist.github.com/bszeti/552bf7a1f05a75fc2964a4ce7ce889b5]
> and how it can be used in a route:
