------------------------------------------
Summary: Sidecar API Endpoint for Nodetool Compaction Stop
Key: CASSANDRA-20977
URL: https://issues.apache.org/jira/browse/CASSANDRA-20977
Project: Apache Cassandra
Issue Type: New Feature
Components: Sidecar
Reporter: Shalni Sundram
Assignee: Shalni Sundram
This proposal is part of an ongoing project to build bespoke API endpoints to
carry out key Cassandra cluster operations currently managed by nodetool CLI
commands. These APIs will offer 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.
The endpoint in this particular task will be equivalent to the “nodetool stop”
command, which stops compaction processes as a preliminary step for node repair
and restart workflows in Cassandra.
