[jira] [Closed] (FLINK-10243) Add option to reduce latency metrics granularity

["Chesnay Schepler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-10243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chesnay Schepler closed FLINK-10243.
------------------------------------
      Resolution: Fixed
    Release Note: The default granularity for latency metrics was modified. To restore the previous behavior users have to explicitly set the granularity to SUBTASK.

> The latency is currently tracked separately from each operator subtask to each source subtask. The total number of latency metrics in the cluster is thus {{(# of sources) * (# of operators) * parallelism²}}, i.e. quadratic scaling.
> If we'd ignore the source subtask the scaling would be a lot more manageable.
