Crime of the Dirty Type
summary
A practical migration story from Akka Classic to Akka Typed showing concrete tactics: adopt protocol-based messages and Behaviors, use conversion helpers to migrate actors one at a time while keeping both typed and untyped packages in the same build, and avoid big 1–2 day refactors. Demonstrations include using Akka Typed with Akka Persistence, the typed ask pattern with replyTo, and notes about persistence-plugin and API gaps that still need manual fixes.
