Re: [akka-user] [ANNOUNCE] ChanaMQ - an Akka based AMQP messaging broker

2017-07-27 Thread Konrad “ktoso” Malawski 
Dispatchers are documented
http://doc.akka.io/docs/akka/current/scala/dispatchers.html
ForkJoinPool based.

Stages get fused so it’s a bit more tricky than that.

Not too much so far. The major decision of ChanaMQ design is that each 
message is an actor and each queue is an actor etc. So the scalability on 
number of CPU cores or cluster nodes should be well. I can see the CPU 
cores usages are balanced very well.

The only issue is the fluctuated of send/receive rate under some cases, 
I'll try to figure out whether the cause is from client side or ChanaMQ 
server side.

 Attached are benchmarks on my dual Intel Xeon E5620@2.4GHz

 ChanaMQ is designed as a plain Akka sharding cluster, so it should 
 scale out well, although I do not yet take a serious test on it.

[akka-user] how to bind each actor in a pool to a thread

2017-07-27 Thread mc 
Hello,
I have an Akka app that is interfacing with machine learning algorithms 
written in Python.
I'd like to guarantee that each of the Python worker actors is always 
executed using the same thread:
PythonWorker1 -> thread1
PythonWorker2 -> thread2
...

Could someone provide an example on how to achieve that?
Thanks,

M

 Hi,

 We are developing an AMQP messaging broker - ChanaMQ, which is based on 
 Akka actors and Akka streaming. 

 It's currently under Alpha phase, but with lots of AMQP 0-9-1 features 
 implemented, including ack, persistent (Cassandra only so far) etc.

 Methods/Features are not supported yet:

- Connection.SecureOk
- Channel.Flow
- Exchange.Bind / Exchange.Unbind
- Basic.Reject / Basic.Nack / Basic.RecoverAsync / Basic.Recover
- Access.Request
- Tx.Select / Tx.Commit / Tx.Rollback
- Confirm.Select
