> The Sidecar's job management framework (https://issues.apache.org/jira/browse/CASSSIDECAR-150) currently [stores job state in-memory|https://github.com/apache/cassandra-sidecar/blob/0ad3e6fe545abc9254a88bd8de15f24af27d68c7/server/src/main/java/org/apache/cassandra/sidecar/job/OperationalJobTracker.java#L49]. This approach makes some assumptions around the duration of the job and is not resilient, as all job information is lost if the Sidecar restarts. To support long-running operations like `repair` (https://issues.apache.org/jira/browse/CASSSIDECAR-268) that may take days to complete, or cluster-wide operations such as a rolling restart, we must make the job state durable.
> This ticket will track all the subtasks needed to enable the current operational job framework to store operational job state in persistent storage.
