| Interface | Description |
|---|---|
| Plan |
A Plan represents the central data structure of a reservation system that
maintains the "agenda" for the cluster.
|
| PlanContext |
This interface provides read-only access to configuration-type parameter for
a plan.
|
| PlanEdit |
This interface groups the methods used to modify the state of a Plan.
|
| PlanFollower |
A PlanFollower is a component that runs on a timer, and synchronizes the
underlying
ResourceScheduler with the Plan(s) and viceversa. |
| ReservationAllocation |
A ReservationAllocation represents a concrete allocation of resources over
time that satisfy a certain
ReservationDefinition. |
| ReservationConstants | |
| ReservationSystem |
This interface is the one implemented by any system that wants to support
Reservations i.e.
|
| SharingPolicy |
This is the interface for policy that validate new
ReservationAllocations for allocations being added to a Plan. |
| Class | Description |
|---|---|
| AbstractReservationSystem |
This is the implementation of
ReservationSystem based on the
ResourceScheduler |
| AbstractSchedulerPlanFollower | |
| CapacityOverTimePolicy |
This policy enforces a time-extended notion of Capacity.
|
| CapacityReservationSystem |
This is the implementation of
ReservationSystem based on the
CapacityScheduler |
| CapacitySchedulerPlanFollower |
This class implements a
PlanFollower. |
| FairReservationSystem | |
| FairSchedulerPlanFollower | |
| InMemoryPlan |
This class represents an in memory representation of the state of our
reservation system, and provides accelerated access to both individual
reservations and aggregate utilization of resources over time.
|
| InMemoryReservationAllocation |
An in memory implementation of a reservation allocation using the
RLESparseResourceAllocation |
| NoOverCommitPolicy |
This policy enforce a simple physical cluster capacity constraints, by
validating that the allocation proposed fits in the current plan.
|
| PeriodicRLESparseResourceAllocation |
This data structure stores a periodic
RLESparseResourceAllocation. |
| ReservationInputValidator | |
| ReservationInterval |
This represents the time duration of the reservation
|
| ReservationSchedulerConfiguration | |
| ReservationSystemUtil |
Simple helper class for static methods used to transform across
common formats in tests
|
| RLESparseResourceAllocation |
This is a run length encoded sparse data structure that maintains resource
allocations over time.
|
| Enum | Description |
|---|---|
| RLESparseResourceAllocation.RLEOperator |
The set of operators that can be applied to two
RLESparseResourceAllocation during a merge operation. |
