Great, finally an easy migration from JBoss Cache.
Just to know our options in Mobicents future, are there any cons on
using this API? Is there a reason to change a data model/schema coming
from JBoss Cache, that really takes advantage of node relations
parent/child? For instance it's very common to retrieve the set of
childs for a node, another common usage is the removal for a complete
subtree. We have time to rework this data model if it's not the best
usage, we want it as fast as possible, both local and cluster/cloud
modes.
There is nothing wrong with using the Tree API, except that it doesn't perform as well
as the flat API. Now don't let this scare you off - in terms of performance,
we're talking 5 ~ 10% and if the API works better for you, then use it. But you
should benchmark for yourself and see whether you need to extract this extra performance
in exchange for reworking your data model. YMMV. :-)
