[PR] [fix](cache) Follower FE sql cache not invalidated on table metadata replay (#63612) [doris]
924060929 opened a new pull request, #63657:
URL: https://github.com/apache/doris/pull/63657
## Proposed changes
Cherry-pick of #63612 to branch-4.0.
Follower FEs replay metadata changes (e.g. `ALTER TABLE ... RENAME COLUMN`) but
never invalidated the sql cache, so stale entries survived and queries returned
wrong results. Since `enable_sql_cache` defaults to `true` since 4.0, every
multi-FE deployment is affected.
### Additional change for 4.0/4.1
Added `enable_write_op_table_meta_change` FE config (default **false**) to gate
the `OP_TABLE_META_CHANGE` edit log writing:
- `false` (default): master does local cache invalidation only, does NOT
broadcast to followers via journal — zero risk, same behavior as before
- `true`: master broadcasts table metadata change signal to all followers,
enabling follower-side cache invalidation
This allows gradual rollout: deploy the code first, then enable the config
after verification.
