Team,
Will akka persistence support multiple views for one PersistentActor?
If yes, is it recommended to use multiple views for one PersistentActor?
Are there any drawbacks of multiple views for one persistent actor?Also can
any future enhancement in akka persistence impact this behavior?
Hi Endre,
Good idea, I just tried it with a simple Actor with Stash. When using
system.actorOf it works fine, however for that project we create our actors
using an ActorCreator. As soon as I use that for the Actor with Stash I get
the error. I guess that the Creator does not play nice with

@Sean : Good to know :) Pondering whether to jump on the MEAP train to have
an opportunity to comment or to wait for the release so I don't have to
read again updated chapters for fear of losing good changes...
On a more akka topic, if ever there is a wiki somewhere where this list
could be
Hi,
Is it possible to isolate the cluster management messages (such as Member
messages and other system-level messages) could be configured to use a
separate port for application messages (messages defined by user-apps)
through configuration ?
In-banding and out-of-band system messaging
I'm looking forward to your post. Actually, what you've described is pretty
much what we decided was needed as wel. We also decided that etcd + coreos
is not mature enough for us to run in production yet, especially because we
are not confident we are privy of all the quirks.

Sorry for activating this old thread. I also had a little problem regarding
getting good parameters. This is what I did:
Adding this code:
case class Param(name: String){
def unapply(query: Uri.Query): Option[(String)] = {
query.get(name)
}
}
type Segment = String

Hi Joseph -
That's a good idea about the wiki. I was thinking of doing a blog post.
There are a couple other books that are related to your no downtime and
seamless upgrades requirements that I would recommend:

Alessandro, I solved that issue by using weave

Hi
I have been looking at the implementation of akka persistence and would
like to implement some of our functionality in a similar way (batching some
messages for our storage created during the receive method and send them in
one batch after receive, and executing a handler when storage has
We have a akka cluster with 5 nodes and a million processors deployed in
every shard region. Our test scenario like the following,
1. give the first round commands to the region (so these processors are
created)
2. give the second round commands to update the state of the processors.

Hi,
I'm unit-testing an Akka application and I'm triggering an assert upon a
reentrant call to BatchingExecutor, which seems to me to be caused by the
usage of the CallingThreadDispatcher. I'm still working on isolating the
problem, but this does seem like a scenario we easily get into when

That is a know issue https://github.com/akka/akka/issues/15892 in
scaladsl2 in version 0.7 and 0.8. It is fixed in upcoming 0.9.
You can probably work around it by using an Iterator instead.

Would it make sense to add the books to the Akka pages? We currently only have
the “Books” section of the docs, but it might make sense to include it in the
site proper; perhaps as an FAQ? I’d recommend trying it out, going wild, and
submitting a PR to https://github.com/akka/akka.github.com/
Yes, good idea, Roland.
I also want to make the list aware that my new book Reactive Enterprise
with Actor Model is now available as Rough Cuts on Safari Books Online:

Hi Vaughn,
from our side nothing has happened yet: my conclusion is that this thread
contains all the information we need when we start working on this. The reason
why we are waiting is that this work will depend heavily upon Akka Streams and
therefore we are finishing those first, which
