Spark in Real-Time Analytics

Unleash the budding potential of real-time analytics and integration by redeeming the power of Spark streaming and learning.

Today, Spark streaming is used in many organizations as it’s easy and production-ready. It supports the real-time processing and helps to stream data to gain insights into business and further making a change in your decision-making in real-time. For all those who tend to find a detailed definition of Spark is that it is a general engine for large-scale data processing. It is hundred times faster on Hadoop MapReduce memory and ten times faster on disk. It is also quite scalable – the processing of live-data streams.

How can Spark be beneficial in Real-Time:

With Spark it is easy to build full-tolerant streaming applications as it is easy to use, it has full tolerance, it also has high-throughput and it easily combines streaming with batch and interactive queries. Spark streaming supports multiple of inputs/outputs. It reads data from sources like Kafka, Flume, Twitter, and TCP sockets. It receives live data input streams further dividing the data into batches. It can create twenty seconds of data from the input data stream. As soon as the first batch of data is collected, then the new batch gets created from the input data stream. This is a small procedure of how Spark streaming works.

The prominence of real-time and streaming is increasing every year. Stream processing analyzes and performs actions in real-time through continuous queries. Streaming analytics, further, connects you through external data sources enabling applications to integrate certain data into the application flow or to update the external database with the processed information.

Spark in real-time analytics can be used for purpose of these:

To make the operational decisions and further apply them to your business decisions and transactions you make
To apply pre-existing predictive or prescriptive models
To report historical and current data concurrently
To receive alerts based on predefined and on certain parameters
To view displays on dashboards in real-time and constantly change transactional data sets such as the hourly sales of a set of regional grocery stores
Real-Time analytics tells us what is happening right now. Some of the advantages are:

Data Visualization- Data can be placed in a single chart to communicate an overall point. Streaming data can be visualized in real-time to show what is occurring at every single point.

Business insights- Whenever there is an important business event, it first appears in the Perform Actions section on the dashboard.

Increased competitiveness- Business can set trends and benchmarks very easily, they use this data to surpass their competitors who are still using the slower process of batch analysis.

Both, the number of machines and the amount of information which has been created is increasing every single moment. As a result, it becomes difficult to gain insights that are valuable from all the data. So, their Spark streaming plays an important role in playing a big hand in Real-Time analytics. Streaming analytics can prevent less damage to security, manufacturing defects, social media meltdowns. Routine business can be monitored in real time: like manufacturing, IT systems, financial transactions such as authentication and validations. The streaming in real-time can help companies to learn from the customers as well as to cross-sell based on the information presents. The existence of streaming has led to the invention of new business models and further has produced innovations.

To understand the greater significance, it’s important to look at the history of the data analysis. The use of historical data in descriptive, predictive, and prescriptive analytics. Spark has benefited real-time analytics to help transform various business and give them a new name altogether.
