Ruby & Friends Taking Go as an example
... In this talk, I'm going to present several ways
to make such two-way communications between Ruby & Go language.
Richard Lee • CTO @ Polydice, Inc • iCook.tw dev
& ops • Open source lover • @dlackty everywhere
Agenda 1. Why Go language? 2. Go with Ruby using
asynchronous workers 3. Remote Procedure Code 4. Advanced tools
Go Why choose another language when you have Ruby? 1.
Static typing 2. Compiled language 3. Higher level concurrency abstraction (goroutines) 4. No object oriented design
Use cases 1. Command line tools - Heroku's hk 2.
System softwares - Docker 3. DevOps tools - ngrok / packer
Heroku's CLI benchmark ## version $ time heroku version >/dev/null
real 0m1.813s $ time hk version >/dev/null real 0m0.016s ## list $ time heroku apps >/dev/null real 0m3.830s $ time hk apps >/dev/null real 0m0.785s
You don't really understand a language until you use it
in production
Then you might want to use Go in your system
with Ruby
My First Law of Distributed Object Design: Don't distribute your
objects — Martin Fowler
Async processing Use Redis or any message queue based processing.
Resque / Sidekiq friends: • From Ruby to Go • go-workers • goworkers • go-sidekiq • From Go to Ruby • go-resque
go-workers for Resque in action func myFunc(queue string, args ...interface{})
error { fmt.Printf("From %s, %v", queue, args) return } func init() { goworker.Register("MyClass", myFunc) }
...and in Resque class MyClass @queue = :myqueue end Resque.enqueue
MyClass, ['hi', 'there']
Async processing (cont'd) • Pros: • Not fast enough but
quite reliable • easy to scale out • Cons: • Async • Additional setup for queues
Be careful about typing // Expecting (int, string) func myFunc(queue,
args ...interface{}) error { id, ok := args[0].(int) if !ok { return errorInvalidParam } name, ok := args[1].(string) if !ok { return errorInvalidParam } doSomething(id, name) return nil }
Compared to Ruby code class MyClass @queue = :myqueue def
self.perform(i, str) doSomething(i, str) end end
Performance boost • Benchmarked using matrix multiplication a = Matrix[...]
b = Matrix[...] c = a * b puts a * b • 9x faster than Resque • 4x faster than Sidekiq
In some cases, you might need immediate result Then you
need RPC
Remote Procedure Calls Just like function invokation but remotely •
Dynamically-typed • JSON-RPC • MsgPack-RPC • Statically format • Protobuf • Thrift
Dynamically-typed Which means: 1. No need to predefine data format
2. No generated codes for both client & server 3. Quite easy to migrate
JSON-RPC 1. Everybody love JSON! 2. Golang has built-in library
3. Ruby has nice wrappers
JSON-RPC Protocol Can be built on simple TCP connection or
HTTP Request: {"method": "echo", "params": ["Hello JSON-RPC"], "id": 1} Response: {"result": "Hello JSON-RPC", "error": null, "id": 1}
It's demo time.
Client sock = TCPSocket.new "localhost", "5566" call = { method:"RPCMethods.Say",
params:[{"text"=>"Hello, world!"}], id:rand(100) } sock.write JSON.dump call JSON.load sock.readline
Server func (m *RPCMethods) Say(args Args, results *Results) error {
results.Text = args.Text fmt.Println(results.Text) return nil // no error } func (m *RPCMethods) Ping(args Args, results *Results) error { results.Text = "Pong" fmt.Println(results.Text) return nil // no error }
MsgPack 1. MsgPack is efficient binary serialization format 2. Quite
similar to JSON but with binary type 3. Nice packages for most language
MsgPack-RPC 1. MsgPack-RPC is ...RPC using MsgPack 2. Again, nice
packages for different languages
It's demo time.
Client code cli = MessagePack::RPC::Client.new("127.0.0.1", 5566) cli.timeout = 5 v
= cli.call(:echo, "Ruby Conference Taiwan!") cli.close
Statically-typed Which means: 1. Predefine format with special language (IDL)
2. Usually with generated codes 3. Good when you have nice plan
Protobuf 1. Widely used by Google 2. Built in with
Golang 3. However, there's no official RPC mechanism
Thrift 1. Open sourced by Facebook 2. Officially support a
wide range of language 3. Have built in RPC mechanism
Thrift IDL RpcService.thrift namespace go demo.rpc namespace ruby demo.rpc enum
TweetType { TWEET, // 1 RETWEET // 2 } struct Tweet { 1: required i32 userId; 2: required string userName; 3: required string text; 4: optional Location loc; 5: optional TweetType tweetType = TweetType.TWEET }
Thrift in aciton 1. Usually your first start from defining
you service in IDL 2. Generate server / client code using thrift commands 3. Copy that to both side and integrate
But wait, why not just use REST?
RPC v.s. HTTP / RESTful APIs • Persistent connection •
Smaller in size • Easier to implement
Conclusion
Most importantly, learning a new language is always fun and
inspiring
