Flink accumulators are documented here:
https://ci.apache.org/projects/flink/flink-docs-master/apis/programming_gui=
de.html#accumulators--counters

I think Aljoscha's idea is to implement Storm metrics on top of those.

Huangwei, perhaps you can look whether the interfaces match (basically if
Flink accumulators have all the features needed to support the kinds of
metrics that Storm exposes, or if there is a significant impedance
mismatch).
