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.
