> Key: FLINK-21858
> URL: https://issues.apache.org/jira/browse/FLINK-21858
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Affects Versions: 1.12.0, 1.12.1, 1.12.2
> Reporter: Andrew.D.lin
> Priority: Minor
> Labels: auto-deprioritized-major, auto-unassigned, stale-minor
>
> Now operatorName is limited to 80 by
> org.apache.flink.runtime.metrics.groups.TaskMetricGroup#METRICS_OPERATOR_NAME_MAX_LENGTH.
> So propose to limit the maximum length of metric name by configuration.
>
> Here is an example:
>
> "taskName":"GlobalGroupAggregate(groupBy=[dt, src, src1, src2, src3, ct1,
> ct2], select=[dt, src, src1, src2, src3, ct1, ct2, SUM_RETRACT((sum$0,
> count$1)) AS sx_pv, SUM_RETRACT((sum$2, count$3)) AS sx_uv,
> MAX_RETRACT(max$4) AS updt_time, MAX_RETRACT(max$5) AS time_id]) ->
