When you change the actor behavior, the new behaviour will take effect for all subsequent messages +> until the behaviour is changed again.

+Our cluster support however uses a different approach, **Virtual Actor Model**. + +This is a model where each actor appears to *always exist*. +There is no lifecycle as in the classic actor model. +You get a reference to the actor by asking for it's ID. + +e.g. + +```go +hello := shared.GetHelloGrain("abc") +res := hello.SayHello(&shared.HelloRequest{Name: "Proto.Actor"}) +``` + +This will ask the cluster where the 'abc' actor is located. +If it does not yet exist, it will be created for you. + +See Microsoft Orleans for more info about the Virtual Actor Model: +[http://dotnet.github.io/orleans/](http://dotnet.github.io/orleans/) + +## How to + +## Protobuf IDL Definition + +Start by defining your messages and grain contracts. +You do this by using Protobuf IDL files. + +Here is the definition from the `/examples/cluster/shared` example + +```proto +syntax = "proto3"; +package shared; + +message HelloRequest { + string name = 1; +} + +message HelloResponse { + string message = 1; +} + +message AddRequest { + double a = 1; + double b = 2; +} + +message AddResponse { + double result = 1; +} + +service Hello { + rpc SayHello (HelloRequest) returns (HelloResponse) {} + rpc Add(AddRequest) returns (AddResponse) {} +} +``` + +Once you have this, you can generate your code using the protobuf `protoc` compiler. + +**Windows** + +```batch +#generate messages +protoc -I=. -I=%GOPATH%\src --gogoslick_out=. protos.proto +#generate grains +protoc -I=. -I=%GOPATH%\src --gorleans_out=. protos.proto +``` + +## Implementing + +Once the messages and contracts have been generated, you can start implementing your own business logic. +This is essentially a type which is powered by a Proto.Actor actor behind the scenes. + +```go +package shared + +// a Go struct implementing the Hello interface +type hello struct { +} + +func (*hello) SayHello(r *HelloRequest) *HelloResponse { + return &HelloResponse{Message: "hello " + r.Name} +} + +func (*hello) Add(r *AddRequest) *AddResponse { + return &AddResponse{Result: r.A + r.B} +} + +// Register what implementation Proto.Actor should use when +// creating actors for a certain grain type. +func init() { + // apply DI and setup logic + HelloFactory(func() Hello { return &hello{} }) +} +``` + +## Seed nodes + +```go +func main() { + cluster.Start("127.0.0.1:7711") + console.ReadLine() +} +``` + +## Member nodes + +```go +func main() { + cluster.Start("127.0.0.1:0", "127.0.0.1:7711") + + // get a reference to the virtual actor called "abc" of type Hello + hello := shared.GetHelloGrain("abc") + res := hello.SayHello(&shared.HelloRequest{Name: "Proto.Actor"}) + log.Printf("Message from grain %v", res.Message) +} +``` + +## FAQ + +### Can I use Proto.Actor Cluster in production? + +The Proto.Actor Cluster support is in alpha version, thus not production ready. + +### What about performance? + +Proto.Actor Remoting is able to pass 1 million+ messages per second on a standard dev machine. +This is the same infrastructure used in Proto.Actor cluster. +Proto.Actor Cluster however uses an RPC API, meaning it is Request/Response in nature. +If you wait for a response for each call, the throughput will ofcourse be a lot less. +Async Fire and forget for performance, Request/Response for simplicity. diff --git a/cluster/build.sh b/cluster/build.sh new file mode 100644 index 0000000000000000000000000000000000000000..3281957d9cbe9a83f8d18c2a0634b462a693131b --- /dev/null +++ b/cluster/build.sh @@ -0,0 +1,6 @@ +protoc -I=../actor --go_out=. --go_opt=paths=source_relative --proto_path=. cluster.proto +protoc -I=../actor --go_out=. --go_opt=paths=source_relative --proto_path=. gossip.proto +protoc -I=../actor --go_out=. --go_opt=paths=source_relative --proto_path=. grain.proto +protoc -I=../actor --go_out=. --go_opt=paths=source_relative --proto_path=. pubsub.proto +protoc -I=../actor --go_out=. --go_opt=paths=source_relative --proto_path=. pubsub_test.proto + diff --git a/cluster/cluster.go b/cluster/cluster.go new file mode 100644 index 0000000000000000000000000000000000000000..88c9e880dcc5c9b6f37812c80b05ea30d9e5f201 --- /dev/null +++ b/cluster/cluster.go @@ -0,0 +1,262 @@ +package cluster + +import ( + "time" + + "google.golang.org/protobuf/types/known/emptypb" + + "github.com/asynkron/gofun/set" + + "gitee.com/simplexyz/simpleactor-go/actor" + "gitee.com/simplexyz/simpleactor-go/extensions" + "gitee.com/simplexyz/simpleactor-go/log" + "gitee.com/simplexyz/simpleactor-go/remote" +) + +var extensionID = extensions.NextExtensionID() + +type Cluster struct { + ActorSystem *actor.ActorSystem + Config *Config + Gossip *Gossiper + PubSub *PubSub + Remote *remote.Remote + PidCache *PidCacheValue + MemberList *MemberList + IdentityLookup IdentityLookup + kinds map[string]*ActivatedKind + context Context +} + +var _ extensions.Extension = &Cluster{} + +func New(actorSystem *actor.ActorSystem, config *Config) *Cluster { + c := &Cluster{ + ActorSystem: actorSystem, + Config: config, + kinds: map[string]*ActivatedKind{}, + } + actorSystem.Extensions.Register(c) + + c.context = config.ClusterContextProducer(c) + c.PidCache = NewPidCache() + c.MemberList = NewMemberList(c) + c.subscribeToTopologyEvents() + + actorSystem.Extensions.Register(c) + + var err error + c.Gossip, err = newGossiper(c) + c.PubSub = NewPubSub(c) + + if err != nil { + panic(err) + } + + return c +} + +func (c *Cluster) subscribeToTopologyEvents() { + c.ActorSystem.EventStream.Subscribe(func(evt interface{}) { + if clusterTopology, ok := evt.(*ClusterTopology);
