MySQL Shell dump utility - maximum possible chunk size? The documentation https://dev.mysql.com/doc/mysql-shell/8.0/en/mysql-shell-utilities-dump-instance-schema.html mentions that the min chunk size is 128kB. What is the maximum possible chunk size?
The max value is innodb_buffer_pool_size / innodb_buffer_pool_instances or some integral fraction of that.
But why bother changing the setting?  It should not make much difference.
