Re: "I think you all know my feels on JMX." –Super fair - I'd meant to speak in terms of desired outcome ("the feature should be dynamically
configurable at runtime") rather than implementation ("this should be via JMX"). 👍On Nov 1, 2021, at 1:24 PM, David Capwell

<dev@cassandra.apache.org>Subject: Re: [DISCUSS] CEP-3: GuardrailsWithout bike-shedding too much, guardrails would be great, building theminto a more
general purpose framework that limits various dangerous thingswould be fantastic. The CEP says that the guardrails should be distinctfrom the capability
restrictions (https://issues.apache.org/jira/browse/CASSANDRA-8303 ), but I don't see whythat needs to be the case. A system-level guardrail and a
personal-levelguardrail are both restrictions, they just have different scopes, soimplement the restriction framework first, and allow the scopes to beexpanded
as needed?Naming wise, I don't know that I'd actually surface these as "guardrails",but more as general "limits", and having them only
configured via yamlseems like a bad outcomehttps://issues.apache.org/jira/browse/CASSANDRA-8303On Mon, Nov 1, 2021 at 9:31 AM Andrés de la Peña
