   This issue was reviewed as part of the JIRA-migrated backlog triage 
(HUDI-9624).
   
   **Findings: still open.**
   
   A usability follow-up to work that has landed. PR #13517 (`[HUDI-9560] Add 
support event_time metadata`) merged 2025-07-30 under the RFC-97 epic (#17074), 
and this ticket asks that users be told they need to set 
`hoodie.write.track.event.time.watermark` for the tracking to happen.
   
   So the feature exists and the discoverability does not. A config that must 
be set for a feature to do anything at all is the case where silence is most 
costly - the user sees no error and no metadata.
   
   Two cheap options worth stating on the ticket: a docs entry on the 
metadata/event-time page, or a one-time INFO log when event-time metadata is 
requested but the tracking config is off. The second catches users who never 
read the docs.
   
   Keeping this open.
