Hi, I have a question/comment about the behaviour of adaptive load balancing with Ignite 2.7.
I was running a load test on our systems and noticed that eventually we were running out of heap space. Most of the heap was being taken up by the taskTops map within AdaptiveLoadBalancingSpi. Each new task was adding topology data to that map but nothing was ever getting removed. There is a GridLocalEventListener registered in AdaptiveLoadBalancingSpi that will remove tasks from the map if events of type EVT_TASK_FINISHED/EVT_TASK_FAILED are received. The problem is that those event types don't seem to be recorded by default. It seems easy enough to sort by using IgniteConfiguration.setIncludeEventTypes(EventType.EVT_TASK_FINISHED, EventType.EVT_TASK_FAILED) but it's not obvious that this is necessary in the first place. It took me a fair bit of digging through the code and debugging to work out what was going on. Is it possible to improve the adaptive load balancing behaviour a bit? Ensuring the finished/failed event tasks get recorded by default when adaptive load balancing is used perhaps? Thanks, Chris. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
