Flink Jira Bot updated FLINK-21858:
-----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> TaskMetricGroup taskName is too long, especially in sql tasks.

> 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: Major
> Labels: auto-unassigned, stale-major
>
> 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]) ->
> Calc(select=[((MD5((dt CONCAT _UTF-16LE'|' CONCAT src CONCAT _UTF-16LE'|'
