Types

type Cluster

type Cluster struct {
	// contains filtered or unexported fields
}

Cluster represents the Cluster

func New

func New(name string, serviceDiscovery *discovery.ServiceDiscovery, opts ...Option) (*Cluster, error)

New creates an instance of Cluster

func (*Cluster) GetActor

func (c *Cluster) GetActor(ctx context.Context, actorName string) (*internalpb.WireActor, error)

GetActor fetches an actor from the Cluster

func (*Cluster) GetPartition

func (c *Cluster) GetPartition(actorName string) int

GetPartition returns the partition where a given actor is stored

func (*Cluster) NodeHost

func (c *Cluster) NodeHost() string

NodeHost returns the Cluster node Host

func (*Cluster) NodeRemotingPort

func (c *Cluster) NodeRemotingPort() int

NodeRemotingPort returns the Cluster node remoting port

func (*Cluster) PutActor

func (c *Cluster) PutActor(ctx context.Context, actor *internalpb.WireActor) error

PutActor replicates onto the Cluster the metadata of an actor

func (*Cluster) Start

func (c *Cluster) Start(ctx context.Context) error

Start starts the Cluster.

func (*Cluster) Stop

func (c *Cluster) Stop(ctx context.Context) error

Stop stops the Cluster gracefully

type Interface

type Interface interface {
	// Start starts the Cluster engine
	Start(ctx context.Context) error
	// Stop stops the Cluster engine
	Stop(ctx context.Context) error
	// NodeHost returns the Cluster node host address
	NodeHost() string
	// NodeRemotingPort returns the Cluster node remoting port
	NodeRemotingPort() int
	// PutActor replicates onto the Cluster the metadata of an actor
	PutActor(ctx context.Context, actor *internalpb.WireActor) error
	// GetActor fetches an actor from the Cluster
	GetActor(ctx context.Context, actorName string) (*internalpb.WireActor, error)
	// GetPartition returns the partition where a given actor is stored
	GetPartition(actorName string) int
}

Interface defines the Cluster interface

type Option

type Option interface {
	// Apply sets the Option value of a config.
	Apply(cl *Cluster)
}

Option is the interface that applies a configuration option.

func WithHasher

func WithHasher(hasher hash.Hasher) Option

WithHasher sets the custom hasher

func WithLogger

func WithLogger(logger log.Logger) Option

WithLogger sets the logger

func WithPartitionsCount

func WithPartitionsCount(count uint64) Option

WithPartitionsCount sets the total number of partitions

func WithReadTimeout

func WithReadTimeout(timeout time.Duration) Option

WithReadTimeout sets the Cluster read timeout. This timeout specifies the timeout of a data retrieval

func WithShutdownTimeout

func WithShutdownTimeout(timeout time.Duration) Option

WithShutdownTimeout sets the Cluster shutdown timeout.

func WithWriteTimeout

func WithWriteTimeout(timeout time.Duration) Option

WithWriteTimeout sets the Cluster write timeout. This timeout specifies the timeout of a data replication

type OptionFunc

type OptionFunc func(cl *Cluster)

OptionFunc implements the Option interface.

func (OptionFunc) Apply

func (f OptionFunc) Apply(c *Cluster)

Apply applies the Cluster's option
