• I had searched in the issues and found no similar issues.

Description

We plan to implement all SQL functions in other famous DBs, like MySQL, PG, Trino, CK, Hive, and more. Facilitate the users to migrate to Doris. They're very suitable for newcomers as your first Doris PR. So here's the list, you can comment to pick anyone:

Part I. Hive

• context_ngrams @noixcn
• encode, decode
• factorial (Easy) @Czylm
• length (Our length is like Hive's octet_length) (Easy)
• printf
• str_to_map (another map creator)
• levenshtein @lichenran0330
• soundex (Easy)
• mask_show_first_n, mask_show_last_n (Easy)
• mask_hash @cypppper
• inline (lateral view)
• stack (lateral view)
• json_tuple (lateral view)
• parse_url_tuple (lateral view)

See the newest Hive document for these functions' explanation.

Feel free to comment to pick anyone! If one is picked, I will tick it.

Solution

All the guidelines to implement an SQL function are in #48201.
