Since Azul Zing promises less than 4-5ms pause on upto 8TB of heap, it's okay to store data on heap and that way you can also save some efforts which you cant when you use unsafe class with off memory. Please let me know if someone thinks otherwise on this.
One other advantage I see is Azul Zing JVM uses Falcon JIT which uses LLVM to generate more optimized code and that too very fast. For in-memory data grid, since there are lot of computations involved. Since I intend to use Ignite as embedded DB in my Web application server it will be helpful to rely on JVM of that caliber. That's why I am interested in getting feedback from anyone who has used it. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
