Are you tired of dealing with batched events in Azure Stream Analytics? Do you want to ensure that each event is processed individually, one at a time, without any batching? You’re in luck! In this comprehensive guide, we’ll dive into the world of Stream Analytics and explore how to make it always send one event at a time using the LineSeparated serializer.
What is Stream Analytics?
Azure Stream Analytics is a fully managed, real-time analytics service that allows you to process and analyze large volumes of data streaming from various sources. It enables you to gain insights, detect patterns, and trigger actions in real-time, making it an essential tool for IoT, monitoring, and analytics applications.
The Problem with Batching
By default, Stream Analytics batches events together to improve performance and reduce costs. While batching can be beneficial in some scenarios, it can also lead to issues when you need to process each event individually. This is particularly important in applications where real-time processing and event-level accuracy are crucial.
The Consequences of Batching
Batching can have unintended consequences, such as:
- Delayed event processing: Batching can introduce latency, causing events to be processed later than they were received.
- Inaccurate event ordering: Events may be processed out of order, leading to incorrect insights and conclusions.
- Lost or duplicated events: Batching can result in events being lost or duplicated during processing, compromising data integrity.
Enter LineSeparated: The Savior of Single-Event Processing
LineSeparated is a serializer in Stream Analytics that allows you to process events one at a time, eliminating batching and ensuring that each event is handled individually.
How LineSeparated Works
LineSeparated works by serializing each event as a single line of text, separated by a newline character (\n). This serialization format ensures that each event is distinct and can be processed independently, without any batching or grouping.

"type": "LineSeparated",
"serialization": {
"type": "JSON",
"format": "LINE_SEPARATED"
}
}
Configuring LineSeparated in Stream Analytics
To configure LineSeparated in Stream Analytics, follow these steps:
-
Create a new Stream Analytics job or edit an existing one.
-
In the Inputs section, click on the three dots next to your input source and select Serialization.
-
In the Serialization window, select LineSeparated as the serialization format.
-
Choose the JSON format and set the Format to LINE_SEPARATED.
-
Click Save to save your changes.
By following these steps, you’ll ensure that your Stream Analytics job always sends one event at a time using the LineSeparated serializer.
Troubleshooting LineSeparated Issues
While LineSeparated is a powerful tool, it’s not immune to issues. Here are some common problems you might encounter:
Event Corruption
If your events contain newline characters (\n), LineSeparated may corrupt them during serialization. To avoid this, ensure that your events are properly escaped or use a different serialization format.
Performance Impact
Using LineSeparated can introduce additional overhead, particularly for large data volumes. Be mindful of your job’s performance and adjust your configuration accordingly.
Compatibility Issues
LineSeparated might not be compatible with all Stream Analytics features or integrations. Check the official documentation and test your configuration thoroughly to avoid any compatibility issues.
Conclusion
In this article, we’ve explored the world of Stream Analytics and learned how to make it always send one event at a time using the LineSeparated serializer. By following the steps outlined above, you’ll be able to process events individually, eliminating batching and ensuring real-time accuracy.
Remember to troubleshoot any issues that arise and optimize your configuration for performance and compatibility. With Stream Analytics and LineSeparated, you’ll be able to unlock new insights and take your real-time analytics to the next level.
| Serializer | Description |
|---|---|
| LineSeparated | Serializes each event as a single line of text, separated by a newline character (\n). |
| JSON | Serializes events in JavaScript Object Notation (JSON) format. |
| Csv | Serializes events in Comma Separated Values (CSV) format. |
| Avro | Serializes events in Apache Avro format. |

Here is the HTML code for 5 Questions and Answers about “How do I make Stream Analytics always send one event at a time with LineSeparated?”
Frequently Asked Question
Get the inside scoop on making Stream Analytics work seamlessly with LineSeparated output!
I want to send events one at a time with LineSeparated output. How do I configure Stream Analytics?
To send events one at a time, set the `Output batch size` to 1 in your Stream Analytics job configuration. This ensures that each event is sent individually, rather than in batches.
What if I have a large volume of events? Won’t setting the batch size to 1 slow down my pipeline?
While it’s true that sending individual events can increase latency, you can mitigate this by increasing the `Output write frequency` to a shorter interval, such as 1 second. This balances the need for individual events with the need for efficient processing.
How does LineSeparated output format work with individual events?
With LineSeparated output, each event is separated by a newline character (`\n`). When sending individual events, each event will be written to the output as a separate line, making it easy to process and analyze.
Are there any specific use cases where sending individual events is particularly useful?
Sending individual events is particularly useful when you need to trigger real-time alerts or actions based on specific events. This is common in IoT, monitoring, and security use cases, where timely response is crucial.
Can I still use batching with LineSeparated output if I need to optimize for performance?
Yes, you can still use batching with LineSeparated output. To do this, set the `Output batch size` to a value greater than 1, and Stream Analytics will group events together in batches before writing them to the output. This can improve performance, but keep in mind that you’ll need to balance batch size with the need for timely event processing.
