------------------------------------

> Sidecar endpoint to support node decommission operation
> -------------------------------------------------------
>
> Key: CASSANDRASC-151
> URL: https://issues.apache.org/jira/browse/CASSANDRASC-151
> Project: Sidecar for Apache Cassandra
> Issue Type: Improvement
> Components: Rest API
> Reporter: Arjun Ashok
> Assignee: Arjun Ashok
> Priority: Normal
>
> 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 an endpoint that performs the node decommission
> operation on the corresponding Cassandra node. Since decommissioning is a
> long-running operation, this API will leverage the async job management
> framework tracked in CASSANDRASC-150.
