[feature](mtmv)create mtmv can use view#56423

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.

        }
        try {
-            return isMTMVSync(MTMVRefreshContext.buildContext(mtmv), mtmvRelation.getBaseTablesOneLevel(),
+            return isMTMVSync(MTMVRefreshContext.buildContext(mtmv), mtmvRelation.getBaseTablesOneLevelAndFromView(),


getBaseTablesOneLevelAndFromView look like contain views, how can compare mv snapshot to view snapshot?

getBaseTablesOneLevelAndFromView not contains view, but contains table from view, not need compare mv snapshot to view snapshot

        if (LOG.isDebugEnabled()) {
            LOG.debug("mtmv task run, taskId: {}", super.getTaskId());
        }
+        mtmvSchemaChangeVersion = mtmv.getSchemaChangeVersion();


mtmvSchemaChangeVersion is not used?

after task refresh,will compare schema of base table if changed in org.apache.doris.catalog.MTMV#addTaskResult

maybe should add some cases which are views contains mv, and mv is partitioned

fe/fe-core/src/main/java/org/apache/doris/job/extensions/mtmv/MTMVTask.java

    private MTMVRelation relation;
    private StmtExecutor executor;
    private Map<String, MTMVRefreshPartitionSnapshot> partitionSnapshots;
+    private long mtmvSchemaChangeVersion;


what does mtmvSchemaChangeVersion means? why add this

Used to determine whether the SQL of the view has changed during the refresh period. If a change has occurred, the result of this refresh may be incorrect and will be ignored
