Truncation in UI

Hello
When using UI, sometimes Dremio truncates results. We knew UI limited download to 1M rows but it appears that truncation can happen with lower number of rows …
The most annoying point is that truncation information only appears in job detail screen and not in main screen just after the run of the query …
There are 2 questions ?

  • When Dremio chooses to trunc results in UI ?
  • Is there any plan to inform user in UI in a better way ? (not by going to job detail to see if the result was truncated or not …)
    Note : we are running r17.1.

@Arnie Truncation can happen before. For example if the ARROW_WRITER phase has 10 threads then the truncation would happen at 100K per thread, due to skew say only 2 threads had 200K records each then those 2 threads will have truncate are 100K each and the query will stop, so output will only have 200K records in total

Thank you.
Any plan to modify the UI ? To improve UX - that is à pity to go in job detail tab everytime to see if result is truncated or not…
