--------------------------------------

cool, finally a name was chosen.
Manik, unless you started on this, feel free to assign it to me, I've implemented it and am using the feature since some time in staging already.

> As mentioned on the mailing list, when doing
> cache.withFlags(Flag.SKIP_REMOTE_LOOKUP).put( key, value )
> this will cause a CacheLoaderInterceptor to try loading the data, there is no way to prevent this; this is a major performance issue when I'm not interested in the return value of put.
> Apparently SKIP_REMOTE_LOOKUP work only to prevent return values from other nodes, but there's not way to prevent loading from the store. SKIP_CACHE_STORE would correctly skip the read, but I actually want the value to be written to the store, just needing to avoid the read.
