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 (
) 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

Thanks Galder for such a quickly fix.
like Philippe I was not expecting this major issue to be fixed so
fast. I have not tested it myself yet, but will check and inform my
test result tomorrow.
