Where should I store agent conversation history for long-running workflows?

Store long-running agent conversation history outside Catalyst’s durable execution core state. Catalyst only tracks critical workflow progression state, so you can fetch conversation history from production-grade specialized external storage when needed for your agent’s LLM context prompts, requiring reliable external access to avoid critical workflow disruptions. Avoid storing non-critical transient session data directly in Catalyst’s core state store to prevent unnecessary state bloat that impacts execution performance.
