Memory setting for each Storm topology

Hi guys,

We have Strom 1.1.0 managed by Ambari 2.6 and we running 2 different 
topology on Storm.

We set worker.childopts to "-Xmx7168m _JAAS_PLACEHOLDER", but that 
setting for all topology.

And we want to manage memory setting for each topology using Storm 
settings.

Is that possible?

Thanks you in advance,

Vitali

Hello Vitaly,

There was a similar question a few days ago. It seems setting
Config.TOPOLOGY_WORKER_CHILDOPTS in the topology configuration solves the
problem.

Thanks Rui, but my idea is to change it on a per topology basis. The
