…plain (apache#39998) Optimize the explain materialized view info, add double horizontal dividing line between `MATERIALIZATIONS` and`STATISTICS`. Maybe think rewrite fail because` planed with unknown column statistics `, actually is rewrite successfully. Before: | ========== MATERIALIZATIONS ========== | | | | MaterializedView | | MaterializedViewRewriteSuccessAndChose: | | internal#regression_test_nereids_rules_p0_mv_agg_with_roll_up#mv13_1 chose, | | | | MaterializedViewRewriteSuccessButNotChose: | | not chose: none, | | | | MaterializedViewRewriteFail: | | | | Statistics | | planed with unknown column statistics After: | ========== MATERIALIZATIONS ========== | | | | MaterializedView | | MaterializedViewRewriteSuccessAndChose: | | internal.regression_test_nereids_rules_p0_mv_agg_with_roll_up.mv13_1 chose, | | | | MaterializedViewRewriteSuccessButNotChose: | | not chose: none, | | | | MaterializedViewRewriteFail: | | | | | | ========== STATISTICS ========== | | planed with unknown column statistics
…te materialized view (apache#40332) Add `is_used_in_rewrite` property when create mv. Default true; If `is_used_in_rewrite` is false which means the mv would not partion in query rewrite. Such as mv def is as following: CREATE MATERIALIZED VIEW mv1 BUILD IMMEDIATE REFRESH AUTO ON MANUAL DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ( 'replication_num' = '1', 'use_for_rewrite' = 'false' ) AS SELECT k1, k2, count(*) from t1 group by k1, k2; if we run query as following, this mv would not partition in the query rewrite: SELECT k2, count(*) from t1 group by k2;
…m both side of join (apache#40485) This is brought by apache#35562 if partition mv def is as following: CREATE MATERIALIZED VIEW mv1 BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL PARTITION BY (upgrade_day) DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ('replication_num' = '1') AS select t1.upgrade_day, t2.batch_no, count(*) from test2 t2 join test1 t1 on t1.upgrade_day = t2.upgrade_day group by t1.upgrade_day, t2.batch_no; the mv related partition table should `test1`, but now is `test2`, this pr fix this.
