----------------------------------
Assignee: (was: Chandni Singh)
> Improve StatsListener api so that using it with multiple logical operators is
> straightforward
> ---------------------------------------------------------------------------------------------
>
> Key: APEXCORE-69
> URL: https://issues.apache.org/jira/browse/APEXCORE-69
> Project: Apache Apex Core
> Issue Type: Improvement
> Reporter: Chandni Singh
>
> We have discussed theories about using a stats listener on multiple logical
> operators- specifically using stats from downstream operator to slow down
> upstream operator.
> While trying to implement such a StatsListener the processStats() methods
> becomes unwieldy which is mainly because there is no effortless way of
> knowing of which logical operator the stats are. BatchedOperatorStats
> contains operator id but that is assigned at the runtime (not known at the
> time of writing code).
> In past I have used counters to figure out the logical operator but that is a
> hack.
