[jira] [Created] (FLINK-15746) Show tooltip with explanation of the statistics in the WebUI

[Shang Yuanchun (Jira)]

Piotr Nowojski created FLINK-15746:
--------------------------------------

             Summary: Show tooltip with explanation of the statistics in the WebUI
                 Key: FLINK-15746
                 URL: https://issues.apache.org/jira/browse/FLINK-15746
             Project: Flink
          Issue Type: New Feature
          Components: Runtime / Web Frontend
    Affects Versions: 1.10.0
            Reporter: Piotr Nowojski


It would be nice to display explanation of the statistics (for example checkpoint statistics like {{Start Delay}} or {{Alignment Duration}}) in the WebUI in some kind of tool tip, after hoovering over the column.

Maybe we could inject the description from the Flink doc automatically somehow?
