Problem:
When window function in aggregation function, executor would report an error like: Required field 'node_type' was not present!
Example:
SELECT SUM(MAX(c1) OVER (PARTITION BY c2, c3)) FROM test_window_in_agg;
Reason:
When analyze aggregate, analytic expr (window function carrior when analyze) transfered to slot and loss message. So when
serialize to thrift package, TExpr can not determine node_type of analytic expr.
Solved:
We do not support aggregate(window function) yet. So we report an error when analyze.
* Revert "[fix](executor) only mysql connect to set GlobalPipelineTask (#22205)"
* Revert "[feature](executor) using fe version to set instance_num (#22047)"
1. Remove bunch of SQLs related to partition's information
2. Fix the duplicate SQLs submission
3. Fix bug that table's stats not get updated after system job finished
Hive file path may contain temporary directory like this:
drwxrwxrwx - root supergroup 0 2023-03-22 21:03 /usr/hive/warehouse/datalake_performance.db/clickbench_parquet_hits/.hive-staging_hive_2023-03-22_21-03-12_047_8461238469577574033-1
drwxrwxrwx - root supergroup 0 2023-05-18 15:03 /usr/hive/warehouse/datalake_performance.db/clickbench_parquet_hits/.hive-staging_hive_2023-05-18_15-03-52_780_3065787006787646235-1
This will cause error when be try to read these files. Need to filter them during FE plan.
The error message was not good for not exist column while show column stats:
```
MySQL [hive.tpch100]> show column stats `lineitem` (l_extendedpric);
ERROR 1105 (HY000): errCode = 2, detailMessage = Unexpected exception: null
```
This pr show a meaningful message:
```
mysql> show column stats `lineitem` (l_extendedpric);
ERROR 1105 (HY000): errCode = 2, detailMessage = Column: l_extendedpric not exists
```
use three new plan node to represent defer materialize of TopN.
Example:
```
-- SQL
select * from t1 order by c1 limit 10;
-- PLAN
+------------------------------------------+
| Explain String |
+------------------------------------------+
| PhysicalDeferMaterializeResultSink |
| --PhysicalDeferMaterializeTopN |
| ----PhysicalDistribute |
| ------PhysicalDeferMaterializeTopN |
| --------PhysicalDeferMaterializeOlapScan |
+------------------------------------------+
```
1. add more logs and make error messages more clear
2. sleep a while between retry analyze
3. make concurrency of sync analyze configurable
4. Ignore internal columns like delete sign to save resources
Problem:
When create view with join in table partitions, an error would rise like "Unknown column"
Example:
CREATE VIEW my_view AS SELECT t1.* FROM t1 PARTITION(p1) JOIN t2 PARTITION(p2) ON t1.k1 = t2.k1;
select * from my_view ==> errCode = 2, detailMessage = Unknown column 'k1' in 't2'
Reason:
When create view, we do tosql first in order to persistent view sql. And when doing tosql of table reference, partition key
word was removed to keep neat of sql string. But here when we remove partition keyword it would regarded as an alias.
So "PARTITION" keyword can not be removed.
Solved:
Add “PARTITION” keyword back to tosql string.
