Subject Can a topology be configured to force a maximum of 1 executor per worker?
Date Wed, 05 Feb 2014 16:06:33 GMT
Suppose that you have a bolt whose tasks are not thread safe but you
still want parallelism.  It seems that this could be achieved via
multiprocessing by forcing a maximium of 1 executor per worker.  With
this constraint, if you chose a parallelism hint of 4 (with default
executors) you would get 4 tasks in 4 executors each running in a
separate worker.  Can this constraint be configured?
