Andrés Beck-Ruiz updated CASSSIDECAR-460:
-----------------------------------------
Change Category: Operability
Complexity: Normal
Component/s: Rest API
Status: Open (was: Triage Needed)
> 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
> Components: Rest API
> Reporter: Andrés Beck-Ruiz
> Assignee: Andrés Beck-Ruiz
> Priority: Major
>
> 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.
