Hi, I have a few questions:
1. 'Example of a running topology' in the Wiki: http://storm.apache.org/documentation/Understanding-the-parallelism-of-a-Storm-topology.html
The yellow bolt is configured with a parallelism hint of 6. Since no number of tasks is specified, it imlicitly is equal to parallelism hint. Now in the next section the number of executors is increased to 10 which does not make too much sense since # of tasks = const = 6, right?
2. The topology is rebalanced to use 5 instead of 2 workers. This assumes, that 3 additional worker slots are available on the cluster!?
3. I read the Storm @ Twitter paper where they write 'A task is strictly bound to an executor because that assignment is currently static.' This is outdated, right? How else would the rebalancing work?
4. An executor can only execute tasks of the same component. These tasks are executed in serial. Right?
Thanks, Johannes
