             Summary: Sidecar endpoint to support on-demand repair operation
                 Key: CASSSIDECAR-268
                 URL: https://issues.apache.org/jira/browse/CASSSIDECAR-268
             Project: Sidecar for Apache Cassandra
          Issue Type: Improvement
            Reporter: Arjun Ashok


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 repair operation for a given keyspace with several options ranging from the set of tables, token-range to be repaired, type of repair (incremental vs full) etc.. Since repair is a long-running operation, this API will leverage the async job management framework tracked in CASSANDRASC-150.
