Overview

Package ascendalloc implements an ipfscluster.Allocator returns allocations based on sorting the metrics in ascending order. Thus, peers with smallest metrics are first in the list. This allocator can be used with a number of informers, as long as they provide a numeric metric value.

Types

type Allocator

type Allocator struct{}

Allocator implements ipfscluster.Allocate.

func NewAllocator

func NewAllocator() *Allocator

NewAllocator returns an initialized Allocator

func (*Allocator) Allocate

func (alloc *Allocator) Allocate(c *cid.Cid, current, candidates map[peer.ID]api.Metric) ([]peer.ID, error)

Allocate returns where to allocate a pin request based on metrics which carry a numeric value such as "used disk". We do not pay attention to the metrics of the currently allocated peers and we just sort the candidates based on their metric values (from smallest to largest).

func (*Allocator) SetClient

func (alloc *Allocator) SetClient(c *rpc.Client)

SetClient does nothing in this allocator

func (*Allocator) Shutdown

func (alloc *Allocator) Shutdown() error

Shutdown does nothing in this allocator
