Subject [GitHub] flink issue #4110: [FLINK-6900] [metrics] Limit size of metric name componen...

Github user zentol commented on the issue:

    https://github.com/apache/flink/pull/4110
  
    We don't truncate the full identifier, but each individual component before assembling
the final identifier.
    
    I.e. `a.b.<reallyReallyLongSection>.c.d` would become `a.b.<notSoLongSection>.c.d`.
    
    The primary cause of this currently are the names of WindowOperators or long task chains;
but given that the sections are partially controlled by the user there may be more cases.
