Explore the design and implementation of PARTISAN, an alternative runtime system for distributed actor applications, in this conference talk from USENIX ATC '19. Delve into how PARTISAN improves scalability and reduces latency through dynamic overlay selection, named channels, and affinitized parallelism. Learn about the limitations of current distributed actor systems and how PARTISAN addresses these issues. Examine experimental results demonstrating significant improvements in scalability, throughput, and latency compared to Distributed Erlang. Gain insights into the potential impact of PARTISAN on distributed systems development and performance optimization.
