Re: Karaf Cellar as Cache Provider
Posted by Jean-Baptiste Onofre <jb...@nanthrax.net>.
Hi Mike,
Hmmm, ok for the dynamic import.
Can you please create a Jira about that ? As I’m completely refactoring Cellar, I will improve the caching here.
Thanks,
Regards
JB

Re: Karaf Cellar as Cache Provider
Posted by Mike Hummel <mh...@mhus.de>.
Hello JB,
dynamic import is not working. I tested different scenarios but without success.
I'm waiting for a change in cellar. Helpful would be a possibility to use the existing (connected) hazelcast instance with caching capabilities.
If I have time (currently not) I will fork cellar and try my best.
Thx,
Mike
