[jira] [Commented] (FLINK-31358) Display consumed split/partition/queue info on Web UI

    [ https://issues.apache.org/jira/browse/FLINK-31358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17697433#comment-17697433 ] 

Martijn Visser commented on FLINK-31358:
----------------------------------------

I'm actually not sure that this information is even captured in metrics, which would be a first requirement before being able to display it in the UI

> Many data sources have the concept of "split", which is a partition of the whole data (e.g. partition in Kafka, queue in RocketMQ), and each Flink source task is allocated with a subset of splits to consume. When a job is lagging on only a few splits, it would be useful for determining whether it is a data source issue or a Flink issue if users can view which source task consumes which split on Web UI.
