14 Top Data Pipeline Key Terms Explained

Image
 Here are some key terms commonly used in data pipelines 1. Data Sources Definition: Points where data originates (e.g., databases, APIs, files, IoT devices). Examples: Relational databases (PostgreSQL, MySQL), APIs, cloud storage (S3), streaming data (Kafka), and on-premise systems. 2. Data Ingestion Definition: The process of importing or collecting raw data from various sources into a system for processing or storage. Methods: Batch ingestion, real-time/streaming ingestion. 3. Data Transformation Definition: Modifying, cleaning, or enriching data to make it usable for analysis or storage. Examples: Data cleaning (removing duplicates, fixing missing values). Data enrichment (joining with other data sources). ETL (Extract, Transform, Load). ELT (Extract, Load, Transform). 4. Data Storage Definition: Locations where data is stored after ingestion and transformation. Types: Data Lakes: Store raw, unstructured, or semi-structured data (e.g., S3, Azure Data Lake).

How to Unpack a List into Variables Quickly in Python

Here are two examples to unpack a list in Python. You can do it easily by using splat operator. The asterisk in python is called a Splat operator. Here are two splat operators - Single and Double. Below, you will find examples.

1. Single splat operator


Consider, for example, this code:
abc = [1,2,3,4]
print(abc) 

Here the output will be: [1, 2, 3, 4]

What if you didn't want the list output in list format? What if all you wanted was the list of values to be written to the output console? You could write them using a loop and one of the output functions, but Python prefers an easier way:

print(*abc) 1 2 3 4


Unpack List Splat Operators



2. Double splat operator

Here, I have written a function:

def func(x,y,z): 
      return x + y + z

print(func(**d))

It will show '6' as output. Since, I have assigned values for x,y, and z in a dictionary. So by using a double splat operator you assign values to the function.

d = { 
'x': 1, 
'y': 2, 
'z': 3 
}
