Stream data is the future of digital communication, business intelligence, and operations. This is data that is continuously processed from thousands of sources all at once, allowing us to stay up-to-date with user activity on our applications and websites, buying habits on eCommerce stores, gaming progressions, geo-locations on devices, and social media interactions – you name it.

Once analyzed, all these small bits of information give valuable insights into consumer behavior that can help companies make smarter decisions faster than ever before. This is known as streaming analytics or event stream processing.

Companies can now access a wide range of analytics such as correlations, aggregation, filtering, and sampling to gain better insight into their business operations. 

By analyzing social media streams, they can also measure public sentiment around their brand or product which gives them the power to respond quickly when needed situations arise.

Since the processing takes place immediately, streaming data analytics doesn’t require complex computations and the latency is in milliseconds. It also requires scalable, fault-tolerant, and reliable systems. 

Workflow Of Streaming Analytics – Understanding The Mechanism

The general workflow of streaming analytics is as follows:

A. Data Ingestion

A key part of any data analytics project is how you get the necessary information. Data ingestion involves doing just that – pulling in all sorts of information from sensors, applications, and more into an easily accessible streaming platform. 

It needs to be fast, reliable, and able to handle large volumes at a quick pace – gathering everything together so your real-time data analysis can take place quickly.

B. Stream Processing

Data processing is a crucial step when it comes to analyzing data. It involves applying logic and transformations that filter, join, aggregate, or enrich the streams of data so they are ready for analysis. 

Complex queries such as windowing, grouping, and pattern matching must be handled properly while making sure any issues with missing or duplicate records don’t slip through – all this on top of having fault tolerance mechanisms in place should something go wrong.

C. Data Analytics

After cleaning the data, it is time to get your analytical engine running. By applying analytics and machine learning models to your data streams, you can look for anomalies, detect sentiment trends, or make predictions with ease. 

Furthermore, dynamic patterns in the process will provide real-time feedback so that you don’t miss a beat when responding quickly.

D. Data Visualization

Once you have real-time analytics, it is time to visualize them using specialized tools. Visualization helps communicate the insights gained from streaming analytics to stakeholders clearly and concisely.

E. Action & Feedback

Now comes the final part of the streaming analytics process, taking actions based on the insights gained. This may involve triggering alerts, sending notifications, or initiating automated actions. 

Feedback is also collected to evaluate the effectiveness of the actions taken and to improve the streaming analytics process.

How Businesses Can Benefit From Streaming Analytics?

We know you’re always looking for the best options that offer maximum perks and streaming analytics is definitely the one. That’s why we’ve put together this helpful list to show you all of its glittery advantages.

Now that we are familiar with streaming analytics and how it can be used to analyze continuous data patterns, let’s see how it fares against traditional data analytics.

Streaming Analytics Vs Traditional Data Analytics – Everything You Need To Know

Now if you are wondering whether you really need to replace traditional data analytics with streaming analytics, well the answer is pretty simple. You don’t necessarily need to choose one over the other. Both techniques complement each other. Conventional data analytics relies on the batch processing approach and it differs quite a bit from streaming analytics.

So in this section, let’s level things up and see the end-to-end differences between traditional data analytics and streaming analytics. 

I. Data Processing

The main difference between the two approaches lies in how the data processing occurs. Traditional data analytics employs the store-and-analyze workflow. First, the data stays in a data warehouse for some time and is then processed. In comparison, streaming analytics processes data as soon as it arrives – much like preparing notes as the teacher writes on the board.

II. Latency

The second major difference between the two techniques is processing time. Since traditional or batch processing deals with processing large quantities of data, the overall time or latency can be in minutes, hours, or even days. On the other hand, streaming analytics techniques have sub-second latencies since the data volumes are significantly low.

III. Dataset

Batch processing is an efficient way to handle a large amount of data at once, as all information needed for analysis is known in advance. On the other hand, the data streaming process enables the real-time analytic study of incoming data without having any previous knowledge about its size or content.

IV. Hardware

When it comes to processing large data sets, the right hardware requirements can make a big difference. Batch processing requires standard computer specs while data stream processing necessitates high-end gear and specialized architecture because of its greater reliance on speed and agility when handling fluctuating volumes of information. 

Nevertheless, both options utilize considerable resources for their distinct tasks in working with extensive amounts of data.

V. Use Case

Batch processing is a great option if you don’t need instant answers – like backing up data mining or warehousing information. Meanwhile, stream processing can provide you with real-time insights that are essential for activities such as fraud detection, analyzing social media activity, or understanding what your sensors have to say.

Now that we are aware of the differences between streaming analytics and traditional data analytics, let’s see how you can use Kafka for this.

Streaming Analytics With Kafka
