Batch Processing vs Real Time Data Streams

The world generates an unfathomable amount of data, and it continues to multiply at a staggering rate. Companies have quickly shifted from batch processing to data streams to keep up with the ever growing amounts of big data. In this article, weโ€™ll cover what data streaming is, how it differs from batch processing, and how your organization can benefit from real-time streams of data.

Intro to Stream Processing

What is Stream Processing?

Stream processing, also known as data streaming, is a software paradigm that ingests, processes, and manages continuous streams of data while they're still in motion. Data is rarely static, and the ability to empower data as it's generated has become crucial to the success of today's world.

Modern data processing has progressed from legacy batch processing of data towards working with real-time data stream processing. Similarly, consumers now stream data like movies on Netflix or songs on Spotify instead of waiting for the entire movie or album to be downloaded. The ability to process data streams in real-time is a key part in the world of big data.

Read on to learn a little more about how stream processing helps with real-time analyses and data ingestion.

How Data Streaming Works

Legacy infrastructure was much more structured because it only had a handful of sources that generated data and the entire system could be architected in a way to specify and unify the data and data structures.

Modern data is generated by an infinite amount of sources whether itโ€™s from hardware sensors, servers, mobile devices, applications, web browsers, internal and external and itโ€™s almost impossible to regulate or enforce the data structure or control the volume and frequency of the data generated. Applications that analyze and process data streams need to process one data packet at a time, in sequential order. Each data packet generated will include the source and timestamp to enable applications to work with data streams.

Applications working with data streams will always require two main functions: storage and processing. Storage must be able to record large streams of data in a way that is sequential and consistent. Processing must be able to interact with storage, consume, analyze and run computation on the data.

This also brings up additional challenges and considerations when working with data streams. Many platforms and tools are now available to help companies build streaming data applications.

Batch Processing vs Real-Time Streaming - What's the Difference?

All industries that are generating data continuously will benefit from processing streaming data. The use cases typically start from internal IT systems monitoring and reporting like collecting the data streams generated by employees interacting with their web browser and devices and the data generated by its applications and servers. The operations of the company and its products benefit from data stream processing of sensors, equipment, data centers and many more sources.

Since its customers and partners also consume and process streaming data, the ability to send, receive, process streaming data becomes increasingly important. As more companies rely on its data, its ability to process, analyze, apply machine learning and artificial intelligence to streaming data is crucial.

Key Differences and Considerations

Batch Processing vs Real-Time Streaming - What's the Difference?

The key differences in selecting how to house all the data in an organization comes down to these considerations:

  • Batch processing is when the processing and analysis happens on a set of data that have already been stored over a period of time. An example is payroll and billing systems that have to be processed weekly or monthly.
  • Streaming data processing happens as the data flows through a system. This results in analysis and reporting of events as it happens. An example would be fraud detection or intrusion detection. Streaming data processing means that the data will be analyzed and that actions will be taken on the data within a short period of time or near real-time, as best as it can.
  • Real-time data processing guarantees that the real-time data will be acted on within a period of time, like milliseconds. An example would be for-real time application that purchases a stock within 20ms of receiving a desired price.

###Hereโ€™s a breakdown of major differences between batch processing, real-time data processing, and streaming data:

Batch Data Processing Real-Time Data Processing Streaming Data
Hardware Most storage and processing resources requirement to process large batches of data. Less storage required to process the current or recent set of data packets. Less computational requirements. Less storage required to process current data packets. More processing resources required to โ€œstay awakeโ€ in order to meet real-time processing guarantees
Performance Latency could be minutes, hours, or days Latency needs to be in seconds or milliseconds Latency must be guaranteed in milliseconds
Data set Large batches of data Current data packet or a few of them Continuous streams of data
Analysis Complex computation and analysis of a larger time frame Simple reporting or computation Simple reporting or computation

Many companies are finding that they need a modern, real-time data architecture to unlock the full potential of their data, regardless where it resides. Where some real-time data processing is required for real-time insights, persistent storage is required to enable advanced analytical functions like predictive analytics or machine learning. This is where a full-fledged data streaming platform comes in.
