[Branch3.0](Serde) Support hive compatible output format by BePPPower · Pull Request #50469 · apache/doris

BePPPower · 2025-04-27T09:28:12Z

picked from: #49036

Problem Summary: The output format of complex data types are different between Hive and Doris, such as array, map and struct. When user migrate from Hive to Doris, they expect the same format so that they don't need to modify their business code. This PR mainly changes: Add a new option to session variable `serde_dialect`: If set to hive, the output format returned to MySQL client of some datatypes will be changed: Array Doris: ["abc", "def", "", null, 1] Hive: ["abc","def","",null,true] Map Doris: {"k1":null, "k2":"v3"} Hive: {"k1":null,"k2":"v3"} Struct Doris: {"s_id":100, "s_name":"abc , "", "s_address":null} Hive: {"s_id":100,"s_name":"abc ,"","s_address":null} Related apache#37039

Please clearly describe your PR:

What problem was fixed (it's best to include specific error reporting information). How it was fixed.
Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
What features were added. Why was this function added?
Which code was refactored and why was this part of the code refactored?
Which functions were optimized and what is the difference before and after the optimization?
