Currently doris doesn't support datetime type filter stats estimation, but only for date type.
It will cause the filter using datetime type column with the same date and different time computing out a inaccurate selectivity and estimate a wrong row count, such as :
where o.book_time >= '2020-03-01 00:00:00.0' and o.book_time <= '2020-03-01 23:59:59.0';
This pr adds the datetime type(only support hh:mm:ss scale) filter estimation and improve the row count estimation for the above case.
Fix auto analyze doesn't filter unsupported type bug.
Catch throwable in auto analyze thread for each database, otherwise the thread will quit when one database failed to create jobs and all other databases will not get analyzed.
change FE config item full_auto_analyze_simultaneously_running_task_num to auto_analyze_simultaneously_running_task_num
The creation of hudi and iceberg table is disallowed since v1.2.
All these features are covered by hudi/iceberg catalog.
We should remove the code in v2.1
The PR mainly changes:
1. remove the code of hudi/iceberg external table.
2. remove code of iceberg database.
3. disallowed hive external table's creation.
4. disabled odbc,mysql,broker external table by default, and add FE config `disable_odbc_mysql_broker_table` to control it
All cases' results are tested and passed with datetime/date v2
Cases about:
Calculation ( +, -
Kinds of predicates(<, >, =, <>, in, not in, is null, is not null)
Load test(from csv and select into)
Runtime filter
Delete conditions
Key columns(agg/duplicate/uniq model, distributed/partition, bitmap index...)
* [regression test](control) add some regression case for control
```
1. CANCEL DECOMMISSION BACKEND
2. SET REPLICA STATUS
3. CLEAN TRASH
4. SET REPLICA VERSION
5. BAD REPLICA
