Hi,

Apache Storm has this cool feature that one can "rebalance a topology"
during runtime to handle the changes in the streaming workload. Practically
this means adjusting the number of worker machines and the parallelism of
the spouts and bolts.

Translated to Flink terms this would mean changing the numberOfSubtasks
field of the AbstractJobVertices of the JobGraph during runtime (amongst
others, e.g. updating the numberOfOutputChannels in the partitioners
accordingly).

Is there any support for achieving this currently?

Cheers,

Marton
