Real-Time Processing Explained: Benefits, Use Cases & Tools

“The amount of data dealt with in the worlwide society will expand explosively by a factor of 200.”

Big Data is flooding everywhere, and companies require systems to analyze and understand this data as soon as they acquire it.

Achieving a high rate of Data Ingestion, Data Processing, and the display of data for analysis requires the use of Real-time Processing Systems. 

In this quick-start guide, we cover all the aspects of Real-time Data Processing. We will discuss the benefits, architecture, and use cases of real time data processing, Stream Processing (also known as Real-time Streaming Analytics), and lastly discuss Batch vs Real-time Processing.

What Is Data Processing?

• When you process data, you convert the acquired data into a usable form so that it’s easier to analyze and draw conclusions. In most companies, data scientists and engineers are often in charge of gathering and translating this data.
• Companies all around the globe employ Digital or Electronic Data Processing Methods, often known as EDP, to process data using machines, computers, workstations, servers, modems, and processing software programs.
• These tools generate outputs in the form of graphs, charts, images, tables, audio, video extensions, vector files, and other desired formats such that it becomes absorbable for everyone.
• On the whole, Data Processing is a six-step process that involves raw data collection, preparation, sorting, processing analysis, output, and storage.
• If you would like to have a deep dive into these six stages of Data Processing, we have covered them separately in this guide – What is Data Processing? – A Comprehensive Guide.

What Is Real-Time Processing?

• Real-time Processing is a continual input constant Data Processing of incoming data from various Data Sources with very short latency.
• As companies acquire more and more data, the need to analyze this information, more so quickly to be able to create a competitive advantage is becoming imperative.
• Numerous industries, from Network Monitoring, Cybersecurity, and Banks to E-commerce, require Real-time Data Processing to detect frauds, monitor daily transactions, and spot potential growth opportunities. 
• A real-life example of Real-Time Processing is when you travel from “destination A to destination B” using Google Maps.
• Google Maps automatically updates traffic congestion levels using information acquired from various mobile devices and road sensors in that area to suggest to you the optimal & shortest path to reach your destination. 
• Some of the most popular and well-established Real-time Data Processing tools are Apache Spark, Apache Kafka, Amazon Kinesis, Apache Samza, Apache Flume, Azure Stream Analytics, IBM Streaming Analytics, Google Cloud Dataflow, Apache NIFI, and Apache Storm.

Real-Time Processing Architecture

A Real-time Data Processing Architecture comprises the following four components:

• Real-time Message Ingestion: Message ingestion systems ingest incoming streams of data or messages from a variety of sources to be consumed by a Stream Processing Consumer. This service might be built as a simple data store that stores new messages in a folder. However, in many cases, a Message Broker is required to function as a buffer for the messages, which can support scale-out processing and reliable message delivery.

For more information on some of the most popular Message Broker Platforms, visit our helpful guide – Popular Message Broker Platforms for 2022.

• Stream Processing: Stream processors process the ingested messages by performing data processing operations such as filtering and aggregation or preparing them for data analysis.
• Analytical Data Store: Analytical Data Store specializes in big-data preparation and management. They prepare data for analysis before serving it in a structured manner so that it can be queried using analytical software. Analytical Data Stores are also optimized for quick query response times and advanced analytics. 
• Analysis and Reporting: The final step in Real-time Data Processing is to prepare charts, reports, or graphs and provide actionable insights that are readily available and comprehensible to all.

What is Batch Processing?

• Batch Processing, as the name suggests, is the processing of data in bulk. Batch Processing, instead of working in real-time, collects transactions over some time and schedules their processing at some later point.
• Post-processing, it displays the results to a software application or a system from which data scientists, analysts, or engineers can analyze data to make sound decisions. 
• Unlike Real-time Processing, Batch Processing is characterized by more operational flexibility and a slower reaction to changing market conditions.
• A simple example to help you understand how Batch Processing works is when you use washing machines.
  • To wash clothes in a washing machine, you would wait for a cloth pile to build up and then wash your clothes. This mode of operation saves you operational costs and is an efficient way to process your business data.

Pros of Batch Processing

• Involve simple systems that don’t require special hardware or system support.
• Efficient processing of large volumes of data.
• Works offline.
• Capabilities like automation and minimal user involvement.
• Low maintenance.

Cons of Batch Processing

• Limited in scope and capability.
• No real-time updates.
• Debugging Batch Processing systems is complex.
• May require dedicated staff to handle issues.

Real-Time Processing vs Batch Processing

Aligning all of our understanding of real-time processing and batch processing in one table, we get this contrast:

Parameter	Real-time Processing	Batch Processing
Time Frame	Real-time systems have predictable response times. They ingest and process transactions in order of milliseconds.	Batch Processing record transactions and process them at a specified interval.
Processor Availability	Real-time Data Processing demands no time delays, and therefore the processor has to be responsive at all times.	Batch Processing schedules the processing of transactions, so the processor needs to be only available when there is a requirement.
Orientation	Real-time Processing is action or event-oriented.	Batch Processing is measurement-oriented.
Data Handling Capacity	Real-time Data Processing is useful for modest volumes of data. Processing large data volumes requires a significant amount of computation time and processing capability.	Batch Processing is used for large volumes of data.
Resources Involved	Real-time Processing needs high computer architecture and high hardware specifications.	Batch Processing can work with normal computer specifications.
Costs of Implementation	Real-time Stream Processing is complex and costly. It requires a unique combination of hardware and software to deliver speedy outputs.	Batch Processing is the simplest processing method for business applications. It is economical as well.
Maintenance	Real-time Stream Processing is an intricate setup that requires daily updates and backup solutions to regularly receive and supply data.	Batch Processing is less intricate and easy to manage compared to Real-time Stream Processing.

Challenges to Real-Time Processing

Real-time Processing faces two big challenges:

• High-Volume Rapid Ingestion: The ability to process data in real-time at a rapid pace is possible only for modest volumes of data. Ingesting, processing, and storing large volumes of data in real-time is a difficult undertaking, which must be implemented in such a way that there is no congestion in Data Ingestion Pipeline. Moreover, the Data Store must also support high-volume writes to be able to process data quickly.
• Speedy Analytics (also called Operational Analytics): The capacity to create Business Intelligence in real-time is the second barrier when deploying Real-time Processing Systems. Real-time Systems must create alerts or reports in real-time for business employees as soon as data from the source becomes accessible so that they can take action quickly.
