A team ships an internal agent to production. Neat little thing. It reads tickets, calls a couple of internal APIs, sends a Slack notification, and marks the ticket resolved. The engineer who deployed it, in the interest of getting something out the door, gave the agent a copy of their own API token. The token has the permissions of a senior engineer, which is to say it can do almost anything.

• kubectl rollout restart deployment/my-app and eat the disruption.
• Install Reloader so it restarts your pods for you when a Secret changes.
• Mount the Secret as a volume and cross your fingers that your app re-reads the file (spoiler: most apps read it once at boot).

All three share the same flaw: the way you "pick up" a config change is to throw away the process and start a new one. For a rotating database password, that means dropping every in-flight request, cold connection pools, and a latency spike — all to change one string.

I've stared at that status more times than I'd like to admit, usually at the worst possible hour, usually while someone in a chat window is asking why traffic isn't going through. Eleven minutes is about how long it took once, on a cluster that had close to 40% CPU sitting free the entire time. That gap between "there's capacity somewhere" and "this pod actually got scheduled" is what this article is really about.

The best solution here is the Query Store tool. Since its implementation in 2016, this special feature has been storing data about SQL query text, execution plans, and statistics. In addition, unlike the plan cache, it retains this information even after a server restart. However, the trick is to get this data in a user-friendly format.

And yet the same old gap is there. Your Go service calls GetSecret once at startup, decodes the value into a struct, and treats it as immutable for the life of the process. When someone rotates the secret in Key Vault — a new version, the old one disabled — your service has no idea. It keeps using the value it read at boot until the next deploy or pod restart. The rotation was seamless in Azure and invisible to your app, which is exactly the wrong combination.

There's just one problem, and it's the one nobody mentions in the demo: your application has no idea it happened.

It is easy to read this as a race between AI labs, cloud providers, and security vendors, and to ask which one will win.

By the end you have a bespoke ConfigManager in every repo: a loader, a fetcher, a refresh loop, a mutex, and a prayer. It is never quite the same twice, it is rarely tested well, and it is exactly the kind of code nobody wants to own.

The incident occurred in the production backend infrastructure of a mobile application. External HTTP traffic was handled by Traefik, deployed on Docker Swarm manager nodes. Traefik ran in swarmMode, used providers.docker, was configured to use the mgp_default network, and had lbswarm disabled so that routing used the required overlay network rather than the Swarm VIP.

One of the critical services was mgp_router-app. It was an entry-point service with two replicas deployed to preserve availability if one of them failed.

The replay job exits. Consumer lag drops. Error rate returns to normal. The dashboard is green enough for everyone to want the incident closed.

The difficult part is not generating a patch. It is ensuring that automated repair changes only code justified by the failure, leaves protected files untouched, and proves that the original failure is actually fixed. Automated program repair research has repeatedly identified patch overfitting as a core risk: a patch can satisfy available tests without being semantically correct. 

Overview

Kafka uses a publish-subscribe model where producers produce events and consumers consume messages. Kafka producers publish events to the broker, and consumers consume the events from the broker. In the meantime, the broker has a different layer of architecture that allows Kafka to be an event streaming platform. The producer, broker, and consumer-related metadata are managed by the Kafka controller, which is elected by ZooKeeper or KRaft. 

• Part 1, Running Sentiment Analysis Inside Neo4j With a Java Plugin, used the VADER lexicon via a pure Java UDF – rule-based, fully local, high throughput.
• Part 2, Wasm Inside Neo4j: Building the Example That Didn't Exist, embedded a Wasm runtime inside a Java UDF using wasmtime-java — sandboxed, still local, lower throughput.

Part 3 takes a different approach. Instead of bundling a scoring model inside the plugin JAR, we call TypeSafe AI's Jev from inside a Java UDF. Jev is a System One model – it doesn't generate text. It takes a state (the text to evaluate) and a set of typed questions and returns structured decisions with explicit probability and confidence information. No prompt engineering, no JSON schema coercion, no parsing.

Recent research is more nuanced, as one 2026 study of real repositories found AI-generated code to be more verbose and to exhibit different duplication patterns, while another maintenance study found lower subsequent maintenance activity for sampled AI-generated files than for comparable human-generated files. A 2025 controlled study likewise found fewer defects in some LLM-generated solutions but also structural problems on harder tasks. The operational conclusion is therefore not that generated code is inherently inferior, but that code volume can grow faster than governance capacity. 

The trouble shows up later, when the same agent is asked to inspect infrastructure, parse OpenAPI specs, write docs, answer developer questions, and call operational tools. The system prompt turns into a wall of text. Tool selection gets flaky in ways you can't reproduce. Someone tunes the prompt to fix documentation quality and quietly breaks spec analysis, and nobody notices for a week.

1. The Fixed Knowledge Cutoff: Model intelligence is inherently restricted to its training data window, making it blind to real-time changes.  
2. The "Air-Gap" Limitation: Out of the box, LLMs cannot securely interact with external systems or private APIs on their own.

Historically, developers bypassed these hurdles by writing fragile, ad-hoc API wrappers or custom orchestrators. Enter the Model Context Protocol (MCP): an open standard designed to standardize how AI applications safely connect to external data sources and execution environments.

In this article, we will explore the core architecture of MCP, look at why the Azure MCP Server is a game-changer for cloud engineers, and walk through a step-by-step guide to configuring it inside Visual Studio Code.

Cybernews reported that the exposed material includes customer records, billing data, payment system screens, and unreleased product features. The agents appear to have completed the task using access they already held, but the route they took exposed data publicly.

During an early proof of concept, the questions are usually foundational:

This is a hands-on build of the whole path: train a model with Azure ML's SDK, register it, deploy it behind a managed endpoint, and then wire that endpoint into a Foundry agent as a function tool, so a conversational agent can call your custom model mid-conversation the same way it would call any other tool.

In a traditional monolithic application, maintaining data consistency is straightforward. If you need to create a new order and update warehouse inventory, you wrap the logic inside a single database transaction:

@Transactional
public void placeOrder(OrderRequest request) {
    orderRepository.save(request.toOrder());
    inventoryRepository.decrementStock(request.getItemId(), request.getQuantity());
}
