Remove Accumulators at runtime

Hello,

We can add an accumulator using the following call:
getRuntimeContext().addAccumulator(NAME, ACCUMULATOR);

Is there a way to remove the added accumulators at runtime? 

Regards,
Pedro Chaves

I see, this is not possible with accumulators. You could wrap all
counts in a single metric and update that one. Check out Flink's
metrics:

Hi,

I'm building a system that maintains a set of rules that can be dynamically
added/removed. I wanted to count every element that matched each rule in an
accumulator ( I have several parallel instances). If the rule is removed so
should the accumulator.

Hey Pedro! No, this is not possible. What your use case for this?
