Re: Why Ignite use so many heap space?

Hi! You said: "And it still uses 80%-85% of heap memory after I stop my application", I assume you mean your client application ? So after a GC it will still stay at 80% java heap usage ? I assume you are using off-heap memory ? I am not sure what the problem is, I am running an application

Hi we use ignite as our searching backend. Our cache is in replicated mode and primary_sync. Our query is more like the following. We find that that the query time is the sum of two sub-select query. Since our two sub select query is independent, is there a way to run them in parallel ? Thanks
