There is no place where Big Data is absent! Here are some magnificent facts reported by every minute, where end-users watch 4.15 million YouTube videos, tweet 456,000 on Twitter, upload 46,740 photos on Instagram, and 510,000 comments with 293,000 status updates on Facebook!

Why is Big Data such a voluminous data set?

Big Data refers to the large volume of data that cascades in from various data sources with different formats to obtain enumerable benefits. Almost 90% of today’s data has been caused in the past 3 years. This data comes from many sources like Social Networking, E-commerce, Weather Station, Telecom companies and Share Market. Big Data holds diverse information that comes up with increasing volumes, huge quantities, and ever-higher velocity. Big Data is categorized into structured data types that carry quantitative information or unstructured data types that carry qualitative information.

Hadoop a java based Framework

Hadoop is an open-source framework written in Java that allows to reserve and exercise of Big Data in a distributed environment across clusters of computers using simple programming structures. Its format is designed to bioprocess a single server to thousands of machines, each offering local computations and storage. HDFS is used for storage (Hadoop Distributed File System), which allows fast recovery from hardware failure and storing data of numerous formats across a cluster. The second one is YARN, resource management in Hadoop, which allows parallel processing over the data which is stored across HDFS.

Spark in Big Data

Spark was introduced for its Advanced Analytics by Apache Software Foundation for speeding up the Hadoop computational computing software process. It relies on Hadoop because of its own cluster management system in spark. This is recognized as  “The King Of  Big Data”. Data Processing, it’s one of the largest open-source projects. This makes use of Hadoop in two ways – one used for storage purposes and the second used for processing. Internet swapping like Yahoo, Netflix, eBay, etc on a large scale. Apache Spark always appraises it as the future of the Big Data platforms.

Data Ingestion in Big Data and ETL?

Data ingestion assembles data and then it stores in a Data processing system from where it is easily accessible. Data processing systems include Search engines and databases. Data ingestion is the process of carrying data from one or more start points to a destination site for further processing and analysis. ETL stands for “Extract, Transform, Load,” these three processes together move data from one database, multiple databases, or other sources to type a data warehouse, a unified repository. Big Data Ingestion links with various data sources, extract data, and detect or change the data, while ETL is only concerned with the data that undergo some transformations before data is stored in the data warehouse.

What do we understand about MapReduce

A MapReduce is a data processing framework tool that allows us to process the data parallelly in a distributed form and process on a large data set. It was developed in the year 2004 and published by Google. MapReduce is a programming paradigm that runs in the background of Hadoop that consists of two different tasks Map and Reduce to provide scalability and easy data processing. It is used in various applications are documented clustering, distribute pattern-based searching, used in multiple computing, and also used to MapReduce ion machine learning

What do we understand about Apache Pig?

Apache Pig is used to inspect heavy volumes of data sets representing them as data flows. It provides an abstraction over MapReduce, reducing the complexities while writing a MapReduce program. We can also perform data manipulation operations easily in Hadoop using Apache Pig. We can process huge data sets like Weblogs, streaming online data, and much more. Even Twitter moved to Apache Pig, due to which joining data sets, grouping them all, sorting, and retrieving complete data sets becomes easier and simpler.

What do we understand about  Hive?

Hive is a SQL-based language and data warehouse infrastructure tool that provides SQL-like queries to process structured data in Hadoop. It resides on top of Hadoop to summarize Big Data and makes hive querying language and analyzing large data sets easily. It is built on the top of Hadoop and developed by Facebook. Hive is capable of different sets of storage types like RCFile, plain text, and much more. It uses Indexing for different queries. Hive operates on the server-side of the cluster, works fast, and is used to store metadata.

Conclusion :

As we have entered the era of Big Data known as Game-Changer, Big Data analysis gives permission to look towards wider perspectives of data. Especially it permits the processing of unstructured and structured data altogether. However, huge amounts of sources do not mean that the quality of data is poor to provide reliable results. MTSS is using more analytics to move forward with strategic actions and offer a better customer experience without interruptions.
