[jira] [Commented] (FLINK-34583) Bug for dynamic table option hints with multiple CTEs
[ https://issues.apache.org/jira/browse/FLINK-34583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17838379#comment-17838379 ] Xingcan Cui commented on FLINK-34583: - Hi [~xuyangzhong], thanks for looking into this. I hit the issue when using the Paimon table source. The execution plan looks good. However, the options don't work. It could be a runtime issue or Paimon source implementation bug. I can't remember clearly if Flink generates multiple table sources and then merges them at runtime. If it does, the options may not be merged properly. !image-2024-04-17-16-48-49-073.png! > Bug for dynamic table option hints with multiple CTEs > - > > Key: FLINK-34583 > URL: https://issues.apache.org/jira/browse/FLINK-34583 > Project: Flink > Issue Type: Bug > Components: Table SQL / Planner >Affects Versions: 1.18.1 >Reporter: Xingcan Cui >Priority: Major > Attachments: image-2024-04-17-16-35-06-153.png, > image-2024-04-17-16-48-49-073.png > > > The table options hints don't work well with multiple WITH clauses referring > to the same table.
