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 Prometheus?

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

Apache EventMesh vs Prometheus: 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.

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

◆ Current state

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

◆ Where it's heading

The project is spending its feature budget on start timestamps, appearing across PromQL, TSDB encoding, and remote write V2 in the same release but held behind use-start-timestamps and histograms-st-encoding. Everything else follows the established rhythm of promoting one experimental function per cycle and adding a cloud discovery source. The API deprecations are being staged carefully, warning now and rejecting at the next major.

◆ Prediction

Start timestamps are the obvious candidate to lose their feature flags once the encoding and remote-write halves have run together, and the stats parameter values now warned on will be rejected in the next major.
