Big data represents a large and rapidly growing volume of information that is mostly untapped by existing analytical applications and data warehousing systems.
Voice, video, text communication, online purchases, tax information, census statistics, online reviews, and social media posts all now count as data.
Organizations across the tech world are interested in capturing and analyzing this as it adds significant value to the decision making process.
Processing loads of data involve complex workloads that push the capabilities of traditional data warehousing and data management technologies and techniques.
As much as Big-Data may come in many forms, and the data sizes are colossal. The amount of data being generated daily has increased substantially, as Google’s Eric Schmidt claims that every two days, “we create as much information as we did from the dawn of civilization up until 2003”.
Just how “big” is this data? While most people are used to working with megabytes, gigabytes, and terabytes, large companies and government organizations may have to manage petabytes (1,000 terabytes) or exabytes (1,000 petabytes) of data. Approximately 2.5 quintillion bytes of data are created every day. The continued proliferation of smartphones, tablets, and wearable technology across the globe will add some steam to the big-data train.
To top it all, the data is being generated at a rapid pace. If users around the world send out 100,000 tweets per second, billions of sensor data get generated per minute. This is data generation on a large scale in such a short period of time.
Multiple solutions were discovered to tame big-data into various usages, like the Hadoop ecosystem. Eventually, the techniques became quaint, mainly due to latency (delay) in data input to output analysis.
Real-Time Big-Data is a name given to a more refined and much-needed technique of handling big data today. RTDB, as the name suggests, possesses the ability to process and analyze large volumes of data in real-time or near real-time.
Here are the key differences between Big Data in Real-Time and Non-Real-Time.
With the traditional way of handling big-data, businesses had to wait until their data size grew exponentially. However, with RTBD, even if the data has low incremental volumes and varieties (in real-time), businesses can gain an immediate advantage by deploying their systems.
Simple use cases for RTBD can be tracking sensor data from devices, tracking real-time sales numbers, or tracking user behavior on your website in real-time. Largely RTBD can help a business generate reports, alerts, action triggers, and learning in real-time.
Large internet Organizations like PayPal, which use big data analytics to complete 13 million transactions, processes more than 1.1 PB of data. The organization has gained much via RTBD technology deployment.
No breakthrough technology can make a large-scale impact if it remains expensive, as a result. However, RTBD has made the handling of big-data more affordable and usable for smaller businesses.
For businesses of any size, success is derived by time. As a result, Big Data needs to be embraced now, before it becomes a necessity for survival.
As the consumer appetite is driven by new-age technologies, Real-Time handling of information is the only way forward. The traditional way of handling Big Data via storing and analyzing may not be possible at all. As a result, RTBD is a huge opportunity for business efficiency, innovation leading to profitable success.
Driven by wide adoption across industries, the worldwide market for big data technology and services is expected to grow to $48.6 billion by 2019.

What exactly is Big Data?
The term, big-data, was coined to refer to an ecosystem of problems and solutions arising from the increased inflow of data.As much as Big-Data may come in many forms, and the data sizes are colossal. The amount of data being generated daily has increased substantially, as Google’s Eric Schmidt claims that every two days, “we create as much information as we did from the dawn of civilization up until 2003”.

Real-Time Big Data (RTBD)
As the concept has gained popularity, various techniques have evolved to handle (ingest, manage, use, analyze, and store) big data. The primary challenge is to receive such a large quantity of data, leading to the storage, and finally, data processing and analysis.Multiple solutions were discovered to tame big-data into various usages, like the Hadoop ecosystem. Eventually, the techniques became quaint, mainly due to latency (delay) in data input to output analysis.
Real-Time Big-Data is a name given to a more refined and much-needed technique of handling big data today. RTDB, as the name suggests, possesses the ability to process and analyze large volumes of data in real-time or near real-time.
Here are the key differences between Big Data in Real-Time and Non-Real-Time.
| Differentiation | Non-Real-Time Big Data | Real-Time Big Data |
| Data Storage | Require data to be stored before it is processed, storage is the key element of NRTBD | RTBD relies only on temporary storage in Qs (explained later) |
| Processing / Computation | Works with heavy computation resources ad Queries are implemented on LARGE datasets. | Works with many small/microprocessing units, often distributed across various processors, can work on small machines. |
| Time to Compute | It takes a lot of time to run each discovery job depending on the complexity of the query. More Complex queries take more time. More variety of information also likewise. | Each worker (process) is designed to execute the micro job in fractions of a second, hence with multiple micro-processes, the job gets done within fractions of seconds. |
| Scalability | Low in Scalability as with larger volume and variety of data need different techniques to optimize and scale | Scales seamlessly over a distributed computing environment. Scales faster and uninterrupted With Cloud and Auto-Scaling (like Amazon AWS) |
Key Elements of Real-Time Big Data
| Queues | In a high-velocity system, with different stages of processing, one stage lagging behind others can result in loss of information. The queuing system implements a mezzanine state of data for temporary storage, while the forward system is busy processing earlier data. Just as the forward system completes processing, more data processing from the queue and the workflow continues. Examples: AWS Kinesis, Kafka. |
| Emitters or Spouts | These are set of programs, servers, or microservices working toward splitting data and submitted them for processing by big-data workers. A spout takes the data and sends it to different processing agents – workers - and acts as a data source for the workers. |
| Workers | Execute micro tasks/operations on data received from spouts. Workers can be simple programs written in Node JS, Python, Java, or they can be realized as a Combined Infrastructure and Program Units like Bolts in Apache Storm or AWS Lambda. Workers can also be realized as an interconnected network of processes in a grid environment, where One process acts as a Data Source (Spout) for Next Worker and likewise. |
| Rule Engine | A process that implements a simple “IF THIS THEN THAT” function can come in handy with RTBD, especially when a variety of data is high and Grid of Spouts and Workers is complex. A rule engine, based on data attributes (and/or CONTEXT), can take handy decisions like splitting data, choosing the right worker, choosing the right action. RTBD with RULE ENGINE can form core towards a critical component of Future AI like self-learning/evolving systems. |
| Real-Time Databases | RTDB is an extension of databases to “EMIT” an “EVENT/SIGNAL” on any “CHANGE”. This process has added a powerful contribution to the Real-Time world. In the Real-Time world, it is important to have a forward flow of information i.e., one system completing its job and passing the baton to the next inline system for forward working; RTDB comes very handily. RTDB also allows you to track specific elements or macro-level changes in the database to help you write a forward process on the same. Databases like ReThinkDB claim to have evolved ground up to be RTDB. |
Who needs Real-Time Big Data?
Practically every industry needs RTBD in the near future, be it healthcare, manufacturing, retail, or real estate. RTBD is here to stay.With the traditional way of handling big-data, businesses had to wait until their data size grew exponentially. However, with RTBD, even if the data has low incremental volumes and varieties (in real-time), businesses can gain an immediate advantage by deploying their systems.
Simple use cases for RTBD can be tracking sensor data from devices, tracking real-time sales numbers, or tracking user behavior on your website in real-time. Largely RTBD can help a business generate reports, alerts, action triggers, and learning in real-time.
