How to reload MaxScale cache rules without restarting the service?

I'm looking for a way to apply a new set of rules in /etc/maxscale.rules (JSON) as specified as rules=/etc/maxscale.rules in my cnf file, without restarting the entire MaxScale service.

I am not seeing a MaxAdmin setting that allows manipulating of Cache Filters, but perhaps there is another way?

I also note that a service 'reload' parameter is not implemented, only a service stop/start/restart.

Solution

  • The cache filter rules cannot be reloaded in the current MaxScale version. You can submit feature requests on the MariaDB Jira under the MaxScale project.

    You can work around this limitation by creating a new filter, replacing the original filter with the new one and destroying the old one.
