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.) My wiki account: cambyzju (zhuxiaol...@baidu.com)
