Thread: [Cppcms-users] Cache limit=0 equals unlimited?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Cache limit=0 equals unlimited? Example cppcms_scale

No,

it means empty or no cache...

In case of cppcms_scale, the cache size is defined by the cppcms_scale server, L1 cache size (internal
cache) is defined by its size.

Description cache system with cppcms_scale can work on two levels L1 the local cache that is validated
against the server such that it allows not to transfer data if it is already locally cached.

Ok. Thank you very much.

is a ready made mechanism for invalidating L1 cache on one instance of
cppcms from another instance of cppcms when they use cppcms_scale?
without such a mechanism running with L1 & L2 configuration can be
problematic

Of course. When you access a cache and the object in L1 the request is still sent to a central server
but instead of returing as an ansever that contains the entire object, only the aknowledgement
that your object is up-to-date is sent. So basically you only may for a small ping-pong rather
than entire object transfer.

So it is consistent and transparent as if there were no L1 cache.
