Description
This proposal is part of an effort to introduce bespoke Sidecar APIs to support key operational functionality currently managed through nodetool commands. Introducing these APIs offers several benefits:
- Strong Contract Definition: APIs provide a well-defined contract for both request and response structures, reducing errors in operational tooling by eliminating the need to parse command results.
- Error Handling: A clear response contract allows for meaningful error messages to be communicated to clients, without exposing internal implementation details.
- Input Validation: APIs can incorporate input validation to enhance security by protecting against command injection attacks.
- Version Compatibility: By exposing a standardized interface, APIs ensure compatibility across different Cassandra versions, through the sidecar’s abstraction.
- Access Control: APIs enable fine-grained access control, leveraging permissions and roles associated with client identities for precise authorization.
This specific task introduces a endpoint that vends client connection statistics, equivalent to the `nodetool client stats` API functionality.
