dzr171712 opened a new pull request, #66878:
URL: https://github.com/apache/doris/pull/66878
### What problem does this PR solve?
Issue Number: CIR-27660
Problem Summary:
When finishing a schema change job, the new tablet stats are recalculated
from
the schema change output rowsets. During this process, the tablet's
`last_active_cluster_id` and `last_active_time_ms` may be lost.
In addition, the old tablet index information may be incomplete in the finish
job request, which prevents the meta service from locating the old tablet
stats
as a fallback.
### What changes are included?
- Resolve the complete old tablet index when the finish request does not
contain `table_id`, `index_id`, or `partition_id`.
- Support both normal metadata reads and versioned reads through
`CloneChainReader`.
- Preserve `last_active_cluster_id` and `last_active_time_ms` when updating
schema change tablet stats.
- Reuse active cluster metadata from the following sources in order:
- Existing new tablet stats for versioned reads.
- Old tablet stats.
- Old tablet compact stats for versioned reads.
- Add error handling for malformed stats and metadata read failures.
- Add coverage for both versioned-read and normal schema change flows.
### Test Plan
- Add schema change tests to verify that `last_active_cluster_id` and
`last_active_time_ms` are preserved on the new tablet.
- Cover both versioned and non-versioned schema change jobs.
