35462	Add support JSONArrayAgg	Robert Silén	Lufafa Joshua	"I suggest to add ArrayAgg and related (aggregation) functions for MariaDB to Django. It has been noted in MariaDB Foundation ticket: https://jira.mariadb.org/browse/MDBF-690

E.g. ArrayAgg is mentioned on PostgreSQL specific aggregation functions: 
https://docs.djangoproject.com/en/dev/ref/contrib/postgres/aggregates/#arrayagg

The equivalent in MariaDB is presumably this: 
https://mariadb.com/kb/en/json_arrayagg/

More equivalent MariaDB aggregate functions are listed at the following address. 
https://mariadb.com/kb/en/aggregate-functions/
Some have same name 1:1. I'm guessing e.g. StringAgg could be done with GROUP_CONCAT. 

Feel free to ask more here, or in the MariaDB Foundation ticket. "	New feature	assigned	Database layer (models, ORM)	5.0	Normal		aggregation, ArrayAgg	Hisham Mahmood Sage Abdullah	Accepted	1	0	0	0	0	0
