Mryange opened a new pull request, #69359:
URL: https://github.com/apache/doris/pull/69359
### What problem does this PR solve?
Issue Number: N/A
Related PR: #67738
Problem Summary:
Backport #67738 to branch-4.1. Recursive CTE queries can fail with missing
fragment contexts or rerunnable parameters. Root cause: duplicate reset
requests and materialized ordinary CTE producers shared by independent
recursive controllers. Deduplicate reset entries by fragment ID and BE address,
and inline transitive dependencies of recursive CTEs.
Resolve the CTEInlineTest conflict by adding the test table and imports
required by the new test, without backporting the unrelated CTE pruning changes
from #62828.
### Release note
Fix recursive CTE failures caused by duplicate fragment resets and shared
materialized CTE dependencies.
### Check List (For Author)
- Test
- [ ] Regression test
- [ ] Unit Test
- [ ] Manual test
- [ ] No need to test or manual test
FE unit and regression coverage are included in the backport. Compilation
and tests have not been run for this backport. Diff whitespace checks passed
with the original generated output's trailing blank line preserved.
- Behavior changed:
- [ ] No.
- [x] Yes. Ordinary CTEs transitively referenced by recursive terms are
inlined.
- Does this need documentation?
- [x] No.
- [ ] Yes.
### Check List (For Reviewer who merge this PR)
