I've personally implemented something similar using CQRS. In Akka that roughly translated to an Actor for reading data and an Actor for writing data (using Futures to wrap the actual repository interaction). The actual implementation had a bit more meat to it but the general idea was an Actor for each type of transaction.
I originally got the idea from a BoldRadius presentation by Mike Nash which can be found here: http://boldradius.com/blog-post/VSQCySkAACcA4k5J/easy-scalability-with-akka Well worth the read On Monday, September 19, 2016 at 9:13:52 AM UTC-4, Love Hasija wrote: > > Hi, > > I am trying to create a domain driven repository using Akka.
