issue: #36686
This pr will remove pre-marking segments as L2 during clustering
compaction in version 2.5, and ensure compatibility with version 2.4.
The core of this change is to **ensure that the many-to-many lineage
derivation logic is correct, making sure that both the parent and child
cannot simultaneously exist in the target segment view.**
feature:
- Clustering compaction no longer marks the input segments as L2.
- Add a new field `is_invisible` to `segmentInfo`, and mark segments
that have completed clustering but have not yet built indexes as
`is_invisible` to prevent them from being loaded prematurely."
- Do not mark the input segment as `Dropped` before the clustering
compaction is completed.
- After compaction fails, only the result segment needs to be marked as
Dropped.
compatibility:
- If the upgraded task has not failed, there are no compatibility
issues.
- If the status after the upgrade is `MetaSaved`, then skip the stats
task based on whether TmpSegments is empty.
- If the failure occurs before `MetaSaved`:
- there are no ResultSegments, and InputSegments have not been marked as
dropped yet.
- the level of input segments need to revert to LastLevel
- If the failure occurs after `MetaSaved`:
- ResultSegments have already been generated, and InputSegments have
been marked as Dropped. At this point, simply make the ResultSegments
visible.
- the level of ResultSegments needs to be set to L1（in order to
participate in mixCompaction）
