Types ¶
type Builder ¶
type Builder interface {
// BuildPlacement returns the list of placement vectors
// for object according to the placement policy.
//
// Must return all container nodes if object identifier
// is nil.
BuildPlacement(cid.ID, *oid.ID, netmap.PlacementPolicy) ([][]netmap.NodeInfo, error)
}
Builder is an interface of the object placement vector builder.
func NewNetworkMapBuilder ¶
type Node ¶
type Node struct {
// contains filtered or unexported fields
}
Node is a descriptor of storage node with information required for intra-container communication.
func NewNode ¶ added in v0.38.0
func NewNode(addresses network.AddressGroup, externalAddresses network.AddressGroup, key []byte) Node
NewNode creates new Node.
func (Node) Addresses ¶
func (x Node) Addresses() network.AddressGroup
Addresses returns group of network addresses.
func (Node) ExternalAddresses ¶
func (x Node) ExternalAddresses() network.AddressGroup
ExternalAddresses returns group of network addresses.
type Option ¶
type Option func(*cfg)
Option represents placement traverser option.
func ForContainer ¶
ForContainer is a traversal container setting option.
func SuccessAfter ¶
SuccessAfter is a flat success number setting option.
Option has no effect if the number is not positive.
func WithCopyNumbers ¶ added in v0.37.0
func WithoutSuccessTracking ¶
func WithoutSuccessTracking() Option
WithoutSuccessTracking disables success tracking in traversal.
type Traverser ¶
type Traverser struct {
// contains filtered or unexported fields
}
Traverser represents utility for controlling traversal of object placement vectors.
func NewTraverser ¶
NewTraverser creates, initializes with options and returns Traverser instance.
func (*Traverser) Next ¶
Next returns next unprocessed address of the object placement.
Returns nil if no nodes left or traversal operation succeeded.
func (*Traverser) SubmitSuccess ¶
func (t *Traverser) SubmitSuccess()
SubmitSuccess writes single succeeded node operation.
