Top concepts to learn before learning Data Engineering
If you want to learn data engineering or learning data engineering then this blog is for you. If you want to know required concepts then read this blog till end and follow me for more such blogs.
Let's dive right into the concepts:
1. Multiprocessing
Without multiprocessing data engineering is not possible as you process data on a large scale, and if you want to process data quickly, this concept will help you.
What is multiprocessing?
The simultaneous execution of two or more programmes or instructions by a computer with more than one central processor.
2. Distributed processing
Like multiprocessing distributed processing is equally important for data engineering.
What is Distributed processing?
The use of multiple processors to complete the processing for a single task is known as distributed processing.
3. Logging
Every day, data engineers work with complex ETL pipelines. If he wants to debug the pipeline, he must include logging in his pipeline.
What is Logging?
Logging is a method of recording events that occur when software is run.
Logging is essential for the development, debugging, and operation of software.
4. Exception Handling
This is a critical concept that the data engineer will concentrate on.
No Data Engineer wants their pipeline to be fail in production. This concept was introduced to deal with error.
What is Exception Handling?
The process of responding to the occurrence of exceptions — anomalous or exceptional conditions requiring special processing — during the execution of a programme is known as exception handling.
5. Reusability
Nobody wants to write the same code over and over again, especially data engineers who use this concept to run same ETLs for multiple business use cases.
What is Reusability of code?
The use of similar code in multiple functions is referred to as reusable code in programming.
No, not by copying and pasting the same code from one block to the next, and then from the next to the next, and so on.
Instead, code reusability specifies the method for using similar code without having to rewrite it everywhere.
