Hello all!
I have to create the simple workflow execution engine, that supports
timeouts in its states. The sample made-up definition and the sequence of
the states could be as following:
1) Send the confirmation e-mail to the customer *once*
2) Await the confirmation event for 24 hours
3) If
You're setting the port to 0 but are trying to connect to 2552?

I had found a good blog about the basics of the Akka Actor Model; and
everything looked cool.
However, I then started following up to look at the Akka Docs for
information about Best Practices to handle the complexities of distributed
Fault-Tolerance.
At the moment; the options for handling
It's fine to create more than one in the same jvm. It can be useful for
tests. Be careful to not pass ActorRef instances in a way that would not be
possible if the ActorSystems were in different jvms. Only pass them with
messages. Locate them initially with actorSelection.

I had taken code from the Akka Documentation about handling WebSocket
connections server-side with Akka Streams;
and was able to take the essentials of that to connect to a simple
Javascript Client to send data to the Server, augment it on Server, then
echo it back to the Client.
However, I
For Lagom I wrote json serializer that is using Jackson. You can look at it
for inspiration. It's stored in Cassandra as bytes, but how it's stored is
less important as far as I can see.

Automatic startup on other node is how it is supposed to work, and we have
tests for it. How do you down the dead node?

I'm using Akka 2.3.15 (java) and I'm trying to get a cluster with two
members in two different hosts. Everything runs fine when I start the two
nodes on a single machine, but then when I try to start up the second node
on a different machine, it keeps getting "Association with remote system
Just wanted to check with folks if I had the correct implementation for how
to protect from blowing up memory when working with Akka Streams.
I've merged a Lightbend Blog post's code, with the latest API changes for
Akka v2.4.9, and the latest documentation about buffered streams in the

Possible, yes, but it's rarely a good idea -- ActorSystems are very
heavyweight, and there are almost no
I am wondering if it is possible to create multiple instances of
ActorSystem within a single JVM?
I create my systems as
ActorSystem actorSystem = ActorSystem.create("mySystem", ConfigFactory.load
().getConfig("mySystem"));
and when I call startTime() of each system created it seems to
A few general reactions (personally, I'm using Kryo over Cassandra, so I
can't address the direct questions):
Keep in mind that json is a relatively bulky serialization format -- it's
going to take rather more disk space than more typical options like
protobuf.
In *general*, the serialization
Hi
Reading
http://doc.akka.io/docs/akka/2.4.10/scala/persistence-schema-evolution.html
and thinking about what we currently do, I've concluded that I'd like to
serialize my events as json.
The article suggests I should check the list of plugins to see which
specifically support json. But I
Technically I think the solution holds water, there are appropriate
barriers in place. (multi-materialization aside)
However, as mentioned, fold() would be a much cleaner, safer and
maintainable solution.
