RPC Reinvented: Asynchronous, Durable, and Agent-Ready

Maxim Fateev

What if an API call could safely block for days without timing out? Discover how durable RPC delivers a crash-less programming model perfect for AI agents.

#1 about 2 min

Limitations of standard remote procedure calls

Standard RPC mechanisms fail to guarantee request delivery when clients or connections crash.

#2 about 2 min

Drawbacks of transitioning to event-driven architectures

Abandoning APIs for event-driven callbacks leads to complex code structures and race conditions.

#3 about 4 min

Implementing durable remote procedure calls using databases

Delivering responses to different client instances via request persistence creates fully fault-tolerant RPCs.

#4 about 3 min

Introduction to durable execution and Nexus RPC

Durable execution preserves process state seamlessly to allow writing synchronous code for long-running operations.

#5 about 2 min

Enabling long-running tools for artificial intelligence agents

Durable execution allows LLM tools to safely run asynchronously for weeks without timing out.

#6 about 6 min

Demonstrating workflow recovery with Temporal and OpenAI

A live example shows process state surviving immediate termination using a durable Temporal cluster.

#7 about 2 min

Summary of the Nexus RPC paradigm and use cases

Companies use open-source durable execution platforms for infrastructure automation and mission-critical workflows.
