hello-stephen opened a new pull request, #66005:
URL: https://github.com/apache/doris/pull/66005
### What problem does this PR solve?
During `MULTI_VERSION_WRITE_ONLY`, `commit_index` and `commit_partition`
write versioned
existence keys while reads still prefer legacy tablet metadata. If an
idempotency retry replays
`prepare_index` or `prepare_partition` after the corresponding commit but
before tablets are
created, the legacy existence check misses the committed object and
recreates a `PREPARED`
recycle marker. Recycler can later consume that stale marker and delete
active metadata.
### What is changed?
- Fall back to versioned index/partition existence keys when the legacy
check misses during
`MULTI_VERSION_WRITE_ONLY`.
- Apply the same existence check to duplicate commit handling.
- Add write-only tests covering `prepare -> commit -> replayed commit ->
replayed prepare` and
verify that no recycle marker is recreated.
### Check List
- [x] Code has been formatted with clang-format 16.
- [x] `git diff --check` passes.
- [ ] Cloud unit tests were not run locally because the full Cloud UT
third-party toolchain is
not installed in this workspace; the added tests are included for CI
execution.
