Dmitry Volodin commented on CAMEL-13119:
----------------------------------------
[~BalazsSzeti] this is good idea, but just cache functionality is not enough
for building complete solutions. It requires to invalidate cache, set TTL for
it, manipulate with keys joining or splitting the caches by names, etc.
I'm not sure that it's possible to do all without specific DSL. It will be yet
another simple cache method.
> 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
> Priority: Major
>
> 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:
