@joshuadeanhall I think @Danthar has responded your question on github
Hello how do I disable system logging and only view my logs
@Horusiath > I've fixed that (I hope <fingers crossed>)
I can confirm, it is fixed :-)

Hi,
I am currently investigating "Akka.Cluster.Sharding" via the example "ClusterSharding.Node".
In this example a MessageExtractor is used which requires to know the max count of shards for hashing.
During testing and debug the code I discovered that the "PersistenceId" of the "Customer" actor depends directly on this "max count of shards".
This implies that if this max count ever changes all event stored data has to be migrated?
What to do if the number of shards changes during runtime? Maybe because of load balancing or starting more machines?
Or did I missunderstand that?
@Horusiath Yes @Danthar did. I followed what he said and still have the issue. I added the modified global.asax and also added the non persistent actor which works fine.
To the issue #2243
@Ralf1108 number of shards specified in config should never be changed - rule of thumb says, that it could be 10x maximum number of nodes, you expect to use for your system
so what if the number of nodes increases in future? e.g. a messaging server which has to handle millions of messags instead of thousands....
I've written maximum number of nodes for reason ;)
so if you're using 10 nodes, but expect that in the future you may need 100 of them, then set that value to 10*100=1000
than you start using 100 nodes and increase later to 1000 nodes?
but what if there is the case that if the system grew over and over ... and also over initial plans? :-)
just in case of.... what to do. migrate event store?
set up different sharding strategy ;)
for me it s only important to know that this "max number of shards" is stored with each event store entry
:D
so you mean another message extractor?
@Ralf1108 When you are able to shut your whole system down, you can easily clear everything in your sharding store(s)..
yes, you don't need to follow hash-modulo rule, you can use i.e. some natural boundaries from your application domain - things like region/office identifiers etc.
ok, for a global messaging system e.g. the country id
yes, for example
ok thx :-)
just remember that countries/regions are not equal in size, so you may need to further divide them into smaller parts like US/1, US/2, CAD (2 shards for USA, 1 for Canada, based on user pool)
yes makes sense ! thx for pointing out
@joshuadeanhall my guess is that something blows up on the journal level - do you have any logs?
@Horusiath scala version has ShardIdExtractor, EntityIdExtractor and message extractor, but .net version has only MessageExtractor with three methods. Do you have some strong reasons to join them?
@alexvaluyskiy scala had both - MessageExtractor was used mostly by Java
sigh, I always run into the weirdest edge case shit with Azure
had an old sub migrated to a new sub
didn't migrate my AD settings with me
but since AD can only be managed through old portal
old portal, for some reason, can't see new sub's AD
so I actually can't effect any changes at all through it right now
current thing blocking me from getting CI up and running
@Aaronontheweb how was Australia? :)
rainy :rainbow:
lots of fun overall
attended some interesting talks and met lots of people who I'd known for years on twitter / github but never met in person
:)
I'll try to make it to the conference next time ... lots of friends were presenting ... this time was bad timing :)
got some good suggestions from Akka.NET users who attended the conference, including some who presented about using it
these folks want better DevOps tools / documentation / videos / etc - that and stuff like Akka.Cluster.Tools / Sharding to come out of beta
they've already announced they're going to do it again
since this was their first time in Sydney
:)
I did a karaoke duet with Aaron Powell at the Pluralsight party
hahahaha .. nice .. Aaron is nice. Was Adam (Cogan) there? He loves karaoke :)
and we kept ending up at Baxter's Inn for Scotch
:)
I think he was
I don't recall exactly
recognize the name though
hahaha .. very very loud guy, Microsoft RD, from SSW (they had a big stand there)
you can't miss him
the Readify guys were there in force
couldn't throw a rock in that building without hitting two or three of them
hahahaha .. yeah, I know, they (we) are always there (I'm ex Readify) ;)
seems like a rite of passage to be a .NET developer in Australia :p
gotta have that on the CV
hahahaha ... these days yeah .. it is .. when I joined Readify there were only 12 of us :D those days ...
I left when there were 100 :D
my favorite bit was definitely James Mickens talk: https://twitter.com/Aaronontheweb/status/761136446971404289
I've had some back-and-forth with a few Readify folks via email over the past year or so
didn't realize it was so huge
:)
