Comparing Garbage Collection Strategies in Erlang and JVM/Akka

The episode covers a discussion with Manuel Rubio, author of Erlang/OTP: A Concurrent World, and Dan Plyukhin, creator of the UIGC Actor Garbage Collector for Akka. They explore the actor-based approach to garbage collection both in the Erlang and Akka systems, focusing on their similarities and distinct challenges. The conversation includes topics such as the importance of supervision trees, messages, clustering, and generational garbage collection. Additionally, the challenges of distributed actor garbage collection, such as handling dropped messages and crashed nodes, are examined. The experts also address the impact of immutability on garbage collection in Erlang and the continuing research into optimizing distributed actor garbage collection. Moreover, the discussion emphasizes fault tolerance, asynchronous messaging, and the role of idempotent messaging in maintaining robustness within these systems.
