--------------------------------------------
Summary: Refactor OperationalJob to have data separate from
execution logic
Key: CASSSIDECAR-460
URL: https://issues.apache.org/jira/browse/CASSSIDECAR-460
Project: Sidecar for Apache Cassandra
Issue Type: Sub-task
Reporter: Andrés Beck-Ruiz
Assignee: Andrés Beck-Ruiz
The {{OperationalJob}} class combines data fields (jobId, status,
operationType, node lists) with execution logic. This creates two issues:
1. A {{DurableOperationalJobTracker}} cannot persist a job record before
execution starts because {{OperationalJobManager}} bundles creation and
execution in the same mapping function.
2. Retrieving historical jobs from storage requires extending
{{OperationalJob}} and stubbing execution methods with
{{UnsupportedOperationException}}.
In order to resolve these issues, we should extract a data-only interface from
{{OperationalJob}}, update the {{OperationalJobManager#trySubmitJob}} to
separate creation from execution, and update {{OperationalJobTracker#get}}
handlers to use the data interface for read paths.
