“Education is not the learning of facts, but the training of mind to think.” - Albert Einstein

Skills are crucial to allow any person to manage their daily lives in this ever-changing world. Without the necessary skills, it is difficult to navigate through the challenges that are brought before us from time to time. 

For any business, skilled workers are an asset because they play the most pivotal role in running the operations of the business and developing its reputation and ongoing success. A skilled workforce is the driving energy of an enterprise and without them, an organization simply cannot function. Today, there’s a turf war between companies and employees for employment yet the scene in India’s IT sector is rather discouraging. 

Due to a large number of mismanagements and lethargic employment organization, many aspiring candidates fail to find jobs that are suitable for them and organizations fail to fetch this important workforce for them. As a result, the contribution to our country’s development falls very short of its target. Another tragic fact is the lack of adequate skills among the professionals which is a very concerning issue. Not being in possession of skills that are necessary for an IT job means there is little chance of improvement and personal development as well as for the company’s betterment. This results in people being trapped in the same job for years, working day and night, but never being able to get a salary hike or promotion. 

If you are someone who has been facing this challenge, then it's time to stop worrying.

Overview

In this lesson I will be explaining the different kinds of Data File formats used in Big Data, These are widely used but unspoken of. Anyone aspiring to be a Data Engineer/Data Analyst/ML engineer should be aware of this hidden magic in big data.

Why do we even need a data file format? 

- Imagine storing all information you get in a random order, Will this help? No, it won't 

- Every company gets 10s and 1000s of GB data every day. If these are not stored in a proper format then understanding this data will be difficult. 

- More time you spend sorting through the data, The company is missing out on the opportunity to retain customers or generate more orders/revenue.

This is why data file formats are used in Data lake.

Different kinds of file formats present

We have CSV,JSON,ORC,Parquet,Avro. These are the leading data file formats present.

Which one to choose from and why to choose them completely depends on the use case of a company.

Use-case 1:

If you are looking into total sales data from a table let's say orders, Then this requires 1 column in your table sale_amount to be scanned/quired.

Hence storing this table in columnar format is the best way to go.

File formats to choose: ORC, Parquet

Use-case 2 :

If you are trying to identify the customer behavior, What kind of items are customers placing the order? 

To gather this information you have to scan row-level information spanning multiple columns like user_id, item_name, sale_amount.

Here, Storing the data in row-level format is the right choice to make.

File formats to choose: CSV, JSON, Avro 

Conclusion 

It's important to know that we don't have one fit-all. The question you must ask "How will this data be used? " Based on this file format should be defined.
