[akka-user] Template for Akka Streams & Kafka with Docker & Travis.

[William Narmontas]

Hey all, I built this SBT template last week if you do any Kafka-Akka work:

* https://github.com/ScalaWilliam/akka-stream-kafka-template.g8

Comes with batteries included, and is as simple to use as :

sbt new ScalaWilliam/akka-stream-kafka-template.g8


Feedback, PRs, reports are much welcome.

Regards,
William

As I just mentioned, we're working on it, there will be a replacement ;)

[Konrad Malawski]

Thanks!

It does require it. It is only a getting started tool so you should not
really care. Your normal development you do in whichever thing you want.
It is also being deprecated in favour of new tools we're working on at
Lightbend.

[akka-user] Does Activator require SBT ? Can it work with gradle?

Hi All,

I love the activator tool. Whoever implemented a big thanks! I am wondering 
if it require SBT ? can it work with gradle (since we currently use gradle)?

Thanks!

Thanks! I ended up using LookupEventBus and that solved my problem!

I think I understand it better from what you said. I guess I don't have
separate parent for each group therefore I was looking to see how to group
the child actors but anyways since it is not the standard approach from
what you are saying I would not go that way. I believe I can leverage event
bus  for this
since all I want to do is broadcast different messages to different groups
of actors within a single JVM.

Maybe, not sure what your exact use case is. Picking the simplest thing to
solve your problem is usually a good rule of thumb



Is it recommended to have multiple actors systems within the same JVM? I am
using the Play framework and it has a default Actor system but I wondering
if I should use Actor system provided by the Play framework or create my
own to leverage event bus?

One system is fine, do however read about blocking (google "akka blocking")
to learn how to configure dispatchers to avoid blocking the main dispatcher.



I am assuming the different between pub-sub and event bus is one is
distributed and other is not respectively. isn't it?

Yeah, event-bus is just a quick local thing. Distributed Pub Sub is
distributed pub-sub :)

[akka-user] Re: how to get the number of actors from actor system?

[Dai Yinhua]

Sending ShardRegion.GetClusterShardingStats to a local shard region can get 
all shard regions, and their shards and underlying entities.
