### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version CREATE TABLE t (k1 INT, k2 INT) DUPLICATE KEY(k1) PARTITION BY RANGE(k1) (PARTITION p1 VALUES LESS THAN (10)) DISTRIBUTED BY HASH(k1) BUCKETS 1; ALTER TABLE t ADD TEMPORARY PARTITION tp1 VALUES LESS THAN (10); INSERT INTO t VALUES (1,1),(2,2),(3,3); -- 等 tablet_stat_update_interval_second 让 p1 上报 INSERT INTO t TEMPORARY PARTITION(tp1) VALUES (4,4),(5,5),(6,6),(7,7),(8,8); EXPLAIN SELECT * FROM t TEMPORARY PARTITION(tp1); -- 实际：cardinality = 3（p1 的行数），期望：≈ tp1 的 5 行 -- FE 日志同时出现 "Partition <tp1_id> not exist in table t" 修复方向： getRowCountForPartitionIndex 改成先 idToPartition、再 tempPartitions（temp 的 MaterializedIndex.rowCount 是有效的，TabletStatMgr 已经用 getAllPartitions() 更新过）； getSelectedPartitionRowCount 的"未知分区按比例摊"只用于普通分区，且分母 getPartitionNum()（不含 temp）的语义要对齐； 测试：EXPLAIN SELECT * FROM t TEMPORARY PARTITION(tp1) 的 cardinality 应反映 tp1 的行数。 ### What's Wrong? TEMPORARY PARTITION 的行数不正确, 不是正常partition行数 3 ### What You Expected? 临时分区自己的行数 5 ### How to Reproduce? CREATE TABLE t (k1 INT, k2 INT) DUPLICATE KEY(k1) PARTITION BY RANGE(k1) (PARTITION p1 VALUES LESS THAN (10)) DISTRIBUTED BY HASH(k1) BUCKETS 1; ALTER TABLE t ADD TEMPORARY PARTITION tp1 VALUES LESS THAN (10); INSERT INTO t VALUES (1,1),(2,2),(3,3); -- 等 tablet_stat_update_interval_second 让 p1 上报 INSERT INTO t TEMPORARY PARTITION(tp1) VALUES (4,4),(5,5),(6,6),(7,7),(8,8); EXPLAIN SELECT * FROM t TEMPORARY PARTITION(tp1); -- 实际：cardinality = 3（p1 的行数），期望：≈ tp1 的 5 行 -- FE 日志同时出现 "Partition <tp1_id> not exist in table t" ### Anything Else? no ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
