[ostinru]

From MySQL 8.2 changelog:
https://dev.mysql.com/doc/relnotes/mysql/8.2/en/news-8-2-0.html

INFORMATION_SCHEMA.PROCESSLIST is deprecated and subject to removal in a future MySQL release. As such, the implementation of SHOW PROCESSLIST which uses that table is also deprecated.

It is recommended to use the Performance Schema implementation of SHOW PROCESSLIST instead. As such, performance_schema_show_processlist is also deprecated and subject to removal in a future MySQL release. (WL #15915)
