Description:
According to the https://dev.mysql.com/doc/refman/8.0/en/innodb-memcached-porting-memcached.html daemon_memcached plugin reads  table innodb_memcache.containers  on the server start (or plugin installation).
So, if I want to change configuration for an existing  key, I need to uninstall plugin and install it again. During this process memcached interface is not working and memcached clients requests gonna fail.
Such scheme is not convenient to use it in production.

Would it be possible to make daemon_memcached plugin to read this table periodically ? like every minute or so. 
Or maybe create a special SQL command/function which will force daemon_memcached plugin to read this table again
So any solution which will not stop memcached plugin would be very useful.

Thanks
