Ingestion is the very first step in any real-time architecture: getting events from wherever they originate and bringing them into where they can be processed, analyzed, and acted on.

Events typically start their lives in all kinds of different systems. They might come from Kafka topics in an enterprise environment, AMQP brokers in messaging-based systems, or from Azure-native services like Event Hubs or IoT Hub, which are especially common in cloud and IoT scenarios. Ingestion is what connects those sources into Fabric. Without it, you don’t have anything to work with.

When government funding is tight, it gets harder and harder to get grants to perform fundamental research. The government always wants to see outcomes, and this means that the grants committees need to show outcomes. In turn, this often leads to research funding bodies doing one of three things:

• Only funding research that’s nearly complete
• Only funding well-known researchers with a track record of outcomes
• Only funding research in areas that are already showing promise

Now while at first glance, that might sound a reasonable way to proceed, it’s not.

Once we understand what an event is, the next concept is the stream. A stream is simply a continuous flow of events over time. Instead of looking at events one by one in isolation, a stream is what you get when you treat them as a live feed coming from a source.

For example, imagine an IoT scenario. Each sensor reading from a device is an event. But when you look at all those readings flowing in second by second, that becomes a stream of telemetry. In a financial system, every transaction is an event — but all transactions flowing in from your payment gateway form a transaction stream.

Question:

A database backup was started at 12:00 PM. It completed at 2:00 PM.

When the backup is restored, at what time point will the restored data be?

• 12:00 PM
• 2:00 PM
• Somewhere between 12:00 PM and 2:00 PM

In real-time intelligence, everything starts with the concept of an event. An event is the most fundamental unit of real-time data — it’s simply a record that something happened.

That something could be almost anything, depending on your business. In finance, an event might be a stock trade or a payment transaction. In a web application, it might be a customer clicking a button, logging in, or abandoning a shopping cart. In IoT, it could be a sensor reading like temperature, vibration, or GPS coordinates. Even a server log entry or an error message can be considered an event.

Question:

You have tables that have both constraints and triggers. You need to explain the order of execution for these. Which execution order (from first to last), are used for:

• Check constraints
• After triggers
• Instead of triggers

Microsoft Fabric Real-Time Intelligence is a complete toolkit — an end-to-end set of capabilities that allow you to take streaming data, make sense of it, and act on it.

It starts with event ingestion. Fabric can connect to a wide range of streaming sources: Kafka, Azure Event Hubs, IoT Hub, and many others. That means whether your data is coming from IoT sensors, application logs, or business systems, you can bring it all into Fabric without a lot of custom wiring. Fabric RTI doesn’t force you to pick one source — it’s designed to be open and flexible.

Question:

If a database is configured for simple recovery model, what could stop the truncation of the transaction log being effective, and for the transaction log to keep growing in size?

Answer:

Here are the most frequent reasons:

Batch processing has been the backbone of data analytics for decades. The idea is simple: you collect data over a period of time, maybe hours or a whole day, and then process it in one big chunk. This is how traditional ETL pipelines and overnight data warehouse loads work. It’s efficient when immediacy doesn’t matter — for example, producing a daily sales report each morning.

But the limitation is obvious: if you need to react quickly, batch just doesn’t cut it. By definition, you’re waiting for the batch window to complete before you see the results. If fraud is happening right now, or if a customer is struggling with your app this very minute, a batch report tomorrow morning is far too late.

Section: Administration Level: Intro

Question:

You are restoring a database backup. The restore finished reading pages 10 minutes ago, but the database still shows that it is restoring.

Can you speed up the restoring phase by restarting the server? If so, should you do that? If not, why not?
