TALK
Bridging the CHASM: A Deep Dive into Temporal Server's State Machine SDK
ABSTRACT
CHASM is Temporal’s new server-side state machine SDK, already powering standalone activities, callbacks, Nexus, and the scheduler. In this talk, Roey Berman and Yichao Yang walk through CHASM’s core abstractions—components, fields, archetypes, and tasks—explaining each concept as they build a complete CHASM component from the ground up. Attendees will leave with a clear mental model of how CHASM handles state, task processing, visibility, and multi-cluster replication.
