Why a context engine needs Durable Execution: How Unblocked rebuilt its ingestion backbone on Temporal

What this post added

Unblocked adopted Temporal for its AI context engine's ingestion backbone, migrating from a DIY actor model. The implementation leveraged Temporal's polyglot SDK support and Durable Execution primitive, collapsing orchestration code significantly. The system now runs ~1 million Temporal Workflows daily, self-hosted on Kubernetes, with benefits including deployment-free workflows, elimination of deploy-time database CPU spikes, unified handling of user-triggered and cron flows, and built-in observability.
