Can anyone tell me , how storm schedules multiple topologies? 


For an example if topology A and B both need 2 workers (in total 4 ) but only 3 worker solots
available , which topology will get 2 worker and which will get one worker? 


I know the default scheduler tries to evenly distribute executors to workers but i am interested
in topology level scheduling


My experience says that its a fifo order , the topology submitted first will be always scheduled

Hello ,

I am trying to develop a custom storm scheduler for some specific needs. I wanted to know
if one can control the calling of the scheduler ( or, if it is called periodically , how to
control the frequency )
