[infinispan-dev] Cache Store Does'nt Work Async Whenever Modification is Inside Transaction

Sat Jan 30 03:24:10 EST 2010

I did some tests. Unfortunately my results are not much satisfactory.

I do confirm that now changes are synced in a separate
CoalescedAsyncStore thread, but the aggregate process we discussed
before here ( https://jira.jboss.org/jira/browse/ISPN-116 )  does not
work anymore. I can see that not the only final value but all
modifications are flushed. (i.e. sync at then end of a 100
modifications period results in 100 stores)

The other issue is that only cache.put() worked for me this way, and
it ignored all modification via replace for example.

Let me know if you have done similar tests and your results plz.

Thanks
Amin
