Galder Zamarreño commented on ISPN-1206:
----------------------------------------
Michal, not sure this is a bug. Memcached has no choice, you have to work on the default
cache cos none of the operations allow a cache name to be passed. On the other hand, a
RESTful API for Infinispan allow provisioning of cache name, so maybe a default cache
should be set up for the rest server, i.e. defaultRestCache. This is something that should
be fixed at the EDG level.

Galder Zamarreño commented on ISPN-1206:
----------------------------------------
Reopening this cos it's not a good idea to change the default cache in EDG but leave
it as it is in the Infinispan REST server. As noted in
https://issues.jboss.org/browse/JBPAPP-6777?focusedCommentId=12618719&...
- we can't just change the default cache name in REST because there's an implicit
link between the current default cache name and the associated configuration (even though
it's not documented), and that's been there since day one. So, changing REST's
default cache would effectively break the REST protocol.
So, as proposed in that comment, we could change the default cache name for the Memcached
server because there're no links between the protocol and the cache that's used
underneath. To maintain same logic, the new Memcached default cache would just need to
clone the default cache configuration. That'd be very simple to implement.

Galder Zamarreño commented on ISPN-1206:
----------------------------------------
Btw, some important background info: The reason REST and Memcached can clash in the same
cache is because the type of the key is the same. They both use String keys, so that's
why it could be relatively easy to retrieve something that belongs to a REST server from a
Memcached client.
