Mô tả
**Describe the feature you'd like**
When the table has multiple replicas, when one fails, the leader may change. New leaders of the base_table and aggr_table may be different, causing the base_table may be older than the aggr_table.
We have to invalid the affected entries in the aggr_table, and re-compute to make it right.
