Hi 1. when u say that I should have a constant amount allocated for heap do u mean initially allocated min:4GB, Max 4GB or having a settings of min:1GB , Max: 4GB is allright as well? 2. If i do not configure any on-heap caches does ignite automatically allocate on-heap caches frequent requests or something? 3. Even though it sounds obvious just to verify, when using ignite compute grid data allocated locally (inside the task) during execution of the tasks are still on heap? correct? Thanks
