What is Apache EventMesh?

EventMesh is repositioning as agent infrastructure, adding A2A and MCP to its pub/sub core.

Apache EventMesh releases once a year, each December, and v1.12.0 is a sharp turn from the previous two. Where 1.10 and 1.11 were connector-expansion releases — Kafka, Pulsar, Redis, S3, Slack, WeChat, Canal, MySQL CDC, a chatGPT source connector — 1.12 implements the A2A agent-to-agent protocol and an MCP protocol, with an open issue explicitly framing the goal as AgentMesh infrastructure. The A2A work is substantial: agent registry with heartbeat and capability-based discovery, topic-based task routing over the existing storage plugins, workflow orchestration and task lifecycle with retries and priorities.

What is Rivet?

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

Apache EventMesh vs Rivet: editorial side-by-side

A0.0

EventMesh is repositioning as agent infrastructure, adding A2A and MCP to its pub/sub core.

◆ Current state

Apache EventMesh releases once a year, each December, and v1.12.0 is a sharp turn from the previous two. Where 1.10 and 1.11 were connector-expansion releases — Kafka, Pulsar, Redis, S3, Slack, WeChat, Canal, MySQL CDC, a chatGPT source connector — 1.12 implements the A2A agent-to-agent protocol and an MCP protocol, with an open issue explicitly framing the goal as AgentMesh infrastructure. The A2A work is substantial: agent registry with heartbeat and capability-based discovery, topic-based task routing over the existing storage plugins, workflow orchestration and task lifecycle with retries and priorities.

◆ Where it's heading

The bet is that multi-agent systems need a message fabric rather than point-to-point calls, and that EventMesh's existing pub/sub plumbing — CloudEvents formatting, pluggable RocketMQ/Kafka/Pulsar/Redis backends, connector ecosystem — is that fabric. The design details support that reading: anonymous publishing where the caller does not know which agent will handle a task, capability-based routing, and automatic load balancing across agents advertising the same capability. That is a message broker's answer to agent orchestration. The one-release-per-year cadence is the risk here, since this is a fast-moving area to enter with an annual cycle.

◆ Prediction

Given the AgentMesh framing is filed as an open question rather than a shipped design, expect the next release to formalise it — most likely by building out the MCP protocol work that landed alongside A2A. Whether the annual cadence holds is the more interesting question, since agent protocol surfaces are moving faster than that.

7.5

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

◆ Current state

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

◆ Where it's heading

Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.

◆ Prediction

Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
