Re: [infinispan-dev] Ditching ASYNC modes for REPL/DIST/INV/CacheStores?

It would be a loss of functionality.
As a common example, the AS web session replication cache is configured
for ASYNC by default, for performance reasons.
But it can be changed to SYNC to guarantee that when the request
finishes that the session was replicated.
That wouldn't be possible if you could no longer switch between
ASYNC/SYNC with just a configuration change.
I disagree :).
AS could abstract that configuration detail. IOW, if all Infinispan returned was Futures,
AS or any other client application, has the choice in their hands: do they wait for the
future to complete or not? If they do, they’re SYNC, if not ASYNC. AS can still expose
this and no functionality is lost.
What happens is that SYNC/ASYNC decision stops being a configuration option (bad, bad,
bad) and becomes an actual programming decision Infinispan clients must address (good,
good, good).
Chers,

sync. This would reduce the complexity and configuration of our code base, without
affecting our functionality, and it would make things more logical IMO.
