Thanks Patricks, I will use Backoff.onStop method to create the supervisors for the aggregates and try to restart them incrementally in time. Sebastian. -- >> Read the docs: http://akka.io/docs/ >> Check the FAQ: >> http://doc.akka.io/docs/akka/current/addit

It's right that when you use Cluster Sharding you will not build deep actor hierarchies. The main purpose of the hierarchy is supervision, how to deal with failures. The entities are already managed by Cluster Sharding. You may still add a supervisor actor between Cluster Sharding and the actual en

2017-09-02 Thread Sebastian Oliveri
I´ve read that in order for an akka based software to be well organized and supervised it is recommended to organize actors as a tree instead of having top level actors hanging from the User guardian and this is something I still don´t get the point. I see the point from a performance tip when

Thanks Ronald and Heiko. Turns out, the code that was doing the monitoring \was the culprit. I removed my monitoring, and everything took off from there. I am considering this issue closed, I appreciate your help. On Saturday, August 23, 2014 8:09:25 AM UTC-4, rkuhn wrote: > > > 23 aug 2014

While this is sort of speculative, it looks like you have introduced a bottleneck. Maybe you can use a router for your main actor, resulting in parallelizing entry work (assuming you have multiple cores and enough threads)? Heiko On 23 Aug 2014, at 02:37, Paul Cleary wrote: > I have an actor

I have an actor system that is setup using all of the akka defaults. Nothing in the system has a lot of latency, we are talking about sub millisecond (20 microsecond) latencies. All traffic flows through a single actor to downstream actors. This "main" actor just forwards the message onto chil
