---------------------------------------------
Summary: Guardrails prototype
Key: CASSANDRA-17147
URL: https://issues.apache.org/jira/browse/CASSANDRA-17147
Project: Cassandra
Issue Type: New Feature
Reporter: Andres de la Peña
Assignee: Andres de la Peña
The purpose of this ticket is creating an initial implementation of the
guardrails framework, as well as adding a few simple guardrails using this
framework.
To keep things easy, this initial implementation would only support guardrails
that are triggered on the coordinator, and they would be dynamically updatable
only through JMX.
Once we have this initial framework ready in a feature branch we can have
multiple tickets addressing all the things that would have been left out of the
scope of this ticket, such as:
* Dynamic updates through virtual tables
* Being able to notify about guardrails triggered on replicas
* Using custom exceptions other than {{InvalidRequestException}}.
* Porting existing limits to use the new guardrails framework
* Adding new guardrails beyond the initial ones
The reason for having this simpler prototype is that it will give us a common
ground to parallelize work on the parts mentioned above.
