>                 Key: AURORA-106
>                 URL: https://issues.apache.org/jira/browse/AURORA-106
>             Project: Aurora
>          Issue Type: Task
>          Components: Scheduler
>            Reporter: Bill Farner
>            Priority: Minor
>
> The hierarchical structure will be the crux of the new task store.
> The primary goals are:
> 1. Reduce heap
> 2. Reduce snapshot size.
> 3. Better api for queries and prevent going through the entire task store.
> Proposed hierarchy is:
> Role > Env > Job > Instance > Generation > Task
> Much of what is currently stored in the TaskConfig would move to Generation, and a goal would be to prevent or at least reduce redundant information.  This also involved a composed key structure, where a RoleKey is a string, an EnvKey is a string and a RoleKey, and so on.
