[feature](mtmv)create mtmv can use view by zddr · Pull Request #56423 · apache/doris

zddr · 2025-09-25T02:41:10Z

What problem does this PR solve?

The main changes are as follows:

If the MTMV is in a schema change state, recheck whether the materialized view's SQL statement meets the requirements before refreshing, and check whether the PCT table has changed.
Add a data structure in the StatementContext to store the tables and views directly depended on in the plan.
Add a data structure to store the relationship between materialized views and views.
The location for adding filter conditions during partition refresh has been moved to CheckPolicy, as the previous location could only access the parsed plan.
Clear the snapshot information of the materialized view when a view is deleted or modified.

…atibility (#64412) Introduced by #56423, the field baseViewsOneLevel may be null for MTMVs created before that PR. This causes NPE when querying information_schema.view_dependency: Cannot invoke java.util.Set.stream() because the return value of org.apache.doris.mtmv.MTMVRelation.getBaseViewsOneLevel() is null baseViewsOneLevel is currently only used for tablefunction/MetadataGenerator, so this change is safe. --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
