Strom topology parallelism

Strom topology parallelism

New Contributor

Hello All,

Config conf = new Config();

conf.setNumWorkers(4); // use two worker processes

topologyBuilder.setSpout("blue-spout", new BlueSpout(), 4); // set parallelism hint to 4

in the above case, I am running four process, in each process one spout is associated to that.

can I say,

topologyBuilder.setSpout("blue-spout", new BlueSpout(), 2); // set parallelism hint to 2

only two process having spout and another two process does not have it ?

what about bolt,

one process having bolt running whereas another process does not have the bolt instance running.
