Try to research the jcache api what it offers in this regard.
Not sure if the camel-cache has anything for callbacks on expiry, but
maybe there is some interface you can implement and hook into it.
In other words dive into the code yourself and research the jcache api.
And you are welcome
any guidance is appreciated.
Thanks,
Ganga

Thanks for your suggestion.
However, I did as you recommand :
but I still get the "No configuration found" when I update the bundle.

Hello All,
Is Camel cache available across multiple bundles in Fuse? I.e. can we set it in
one bundle and multiple bundles refer this?
Vanshul
I know of two ways to do that:
1. Export the Endpoint as an OSGi service.
2. Use a middleware endpoint like JMS or some event queue.

Hi,
I'm looking at something that
would automatically flush the cache for the key, run the mybatis query and
cache its result again?
No such thing out of the box. You need to control the cache by
explicit calls to camel-cache operations. You can however consider
using interceptors [1
Hi,
If I controlled the cache by explicit calls to camel-cache operations, I

Traditional way is to have a trigger on the table, and listen to update on a

Hi,
Having a trigger seems to be a simple solution, but does *camel provide a

You can use trigger to invoke Camel endpoint. For example in Postgres

exposed by Camel. Messages from that

camel-cache just let you know the change of the cache and help you change the
content of the cache.
If you want to read the content of the cache, you can use the ehcache API to
access the cache content[1]

If I have a route A which reads data from a dynamic source (data changes

I now have a route B that reads from the cache and sends the exchange to a
