I see a lot of questions unanswered from the last week as well. Does not sound very inspiring Is there another forum where I should be posting?
sorry about the delay.
Firstly, the configuration file needs some changes to conform to the correct schema (you have mixed up 6.0 and 5.0 schemas): infinispan-async-5.3.xml
I have written a small Java program which tests the above and prints out progress, and it is working (although a bit slowly). My recommendation is that you use the new singleFile cachestore available in Infinispan 6.0 which is many times faster. Here's the updated config: infinispan-async-6.0.xml
