> *STR:*
> * Launch Rolling Upgrade on big cluster (500+ node)
> * Proceed to Finalize step
> *Actual Result:*
> Call: 
> {code}
> /api/v1/clusters/c500/upgrades/69/upgrade_groups?upgrade_items/UpgradeItem/status=COMPLETED&upgrade_items/tasks/Tasks/status.in(FAILED,ABORTED,TIMEDOUT)&upgrade_items/tasks/Tasks/command=SERVICE_CHECK&fields=upgrade_items/tasks/Tasks/command_detail,upgrade_items/tasks/Tasks/status&minimal_response=true
> {code}
> This call fails due to timeout. No failed Service Checks shown to user.
> The root of the problem is how the REST API handles subqueries. For every group that matches, it will attempt to retrieve every stage and every task and then produce a slice of results from in-memory comparison.
> This should really go through the JPA layer since it's simple comparisons on DB fields.
