e412dd12e8 [chore](build) Use include-what-you-use to optimize includes (PART II) (#18761)
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.

2d83167e50 [Feature] [Lateral-View] support outer combinator of table function (#9147) 2022-04-24 12:09:40 +08:00
c5718928df [feature-wip](array-type) support explode and explode_outer table function (#8766)
explode(ArrayColumn) desc:
> Create a row for each element in the array column. 

explode_outer(ArrayColumn) desc:
> Create a row for each element in the array column. Unlike explode, if the array is null or empty, it returns null.

Usage example:
1. create a table with array column, and insert some data;
2. open enable_lateral_view and enable_vectorized_engine;
```
set enable_lateral_view = true;
set enable_vectorized_engine=true;
```
3. use explode_outer
```
> select * from array_test;
+------+------+--------+
| k1   | k2   | k3     |
+------+------+--------+
|    3 | NULL | NULL   |
|    1 |    2 | [1, 2] |
|    2 |    3 | NULL   |
|    4 | NULL | []     |
+------+------+--------+

> select k1,explode_column from array_test LATERAL VIEW explode_outer(k3) TempExplodeView as explode_column;
+------+----------------+
| k1   | explode_column |
+------+----------------+
|    1 |              1 |
|    1 |              2 |
|    2 |           NULL |
|    4 |           NULL |
|    3 |           NULL |
+------+----------------+
```
4. explode usage example. explode return empty rows while the ARRAY is null or empty
```
> select k1,explode_column from array_test LATERAL VIEW explode(k3) TempExplodeView as explode_column;
+------+----------------+
| k1   | explode_column |
+------+----------------+
|    1 |              1 |
|    1 |              2 |
+------+----------------+
```
