Subject [jira] [Created] (CAMEL-11114) Create cache DSL
Date Wed, 05 Apr 2017 14:31:41 GMT
Nicola Ferraro created CAMEL-11114:
--------------------------------------

             Summary: Create cache DSL
                 Key: CAMEL-11114
                 URL: https://issues.apache.org/jira/browse/CAMEL-11114
             Project: Camel
          Issue Type: New Feature
            Reporter: Nicola Ferraro
             Fix For: 2.20.0


We should evaluate adding a new "cache" dsl that can be used with all cache components in
Camel. A default implementation may use also caffeine, included in camel-core.

A possible usage example may be:

{code}
from("xxx")
.cache().on("${header.yyy}").ttl(600000) // caches the body
  .to("http4://a-service-that-makes-me-pay-for-each-request.com/api/expensive-endpoint")
  .transform().zzz()
  .to("http4://or-a-service-that-i-can-call-few-times-a-day.com/api/limited-endpoint")
  .unmarshal()
.endCache()
{code}

It should be also useful to protect internal services when using Camel e.g. as a api-gateway
(almost what hystrix does in case of failure of the target host).
