这一事件的深层原因是什么？

深入分析可以发现，A common misunderstanding is treating incremental materialized views as if they have knowledge of the full source table. They do not. An incremental MV is triggered only by new inserts and operates exclusively on the newly inserted block of data. It has no visibility into merges, partition drops, or mutations on the source table. This means that if you alter the source table's data through mutations or partition operations, the materialized view's target table will not be updated to reflect those changes — there is no automatic synchronization. Users must manage this explicitly, either by rebuilding the MV's target table or by using refreshable materialized views for use cases where full-table recomputation is acceptable.
