[Discuss][DSIP] Complex data type ARRAY support

["Zhu,Xiaoli" <zh...@baidu.com>]

Dear All,

Now lots of OLAP systems support ARRAY, MAP, STRUCT complex data types. So complex data types are very important.

First of all, I would like to add ARRAY data type for Doris.
The associated issue: https://github.com/apache/incubator-doris/issues/7570

ARRAY data type implementation is very complex, I would like to complete it by 3 milestone:
Milestone 1: support basic ARRAY data INSERT and SELECT;
Milestone 2: support LOAD or INSERT ARRAY data from most data formats, such as parquet and orc; Rich array functions added;
Milestone 3: advanced array features support, such as High-Order array functions, nested ARRAY data type, and array join.

(Milestone 2 and Milestone 3 will be implemented only on vectorized engine.)

Hi Xiaoli:
I create DSIP-13[1] for this proposal. Please feel free to edit.
