ETL System and Tools:

ETL (Extract, Transform, Load) systems are essential for data integration and analytics workflows. They facilitate the extraction of data from various sources, transformation of the data into a usable format, and loading it into a target system, such as a data warehouse or data lake. Here's a breakdown:


1. Extract: This phase involves retrieving data from different sources, including databases, files, APIs, web services, etc. The data is typically extracted in its raw form.

2. Transform: In this phase, the extracted data undergoes cleansing, filtering, restructuring, and other transformations to prepare it for analysis or storage. This step ensures data quality and consistency.

3. Load: Finally, the transformed data is loaded into the target destination, such as a data warehouse, data mart, or data lake. This enables querying, reporting, and analysis of the data.


ETL Tools:

There are numerous ETL tools available, both open-source and commercial, offering a range of features for data integration and processing. Some popular ETL tools include:


- Apache NiFi: An open-source data flow automation tool that provides a graphical interface for designing data pipelines.

- Talend: A comprehensive ETL tool suite with support for data integration, data quality, and big data processing.

- Informatica PowerCenter: A leading enterprise-grade ETL tool with advanced capabilities for data integration, transformation, and governance.

- AWS Glue: A fully managed ETL service on AWS that simplifies the process of building, running, and monitoring ETL workflows.


Cloud and ETL:

Cloud platforms like Azure, AWS, and Google Cloud offer scalable and flexible infrastructure for deploying ETL solutions. They provide managed services for storage, compute, and data processing, making it easier to build and manage ETL pipelines in the cloud. Azure, for example, offers services like Azure Data Factory for orchestrating ETL workflows, Azure Databricks for big data processing, and Azure Synapse Analytics for data warehousing and analytics.


Python ETL Example:


Here's a simple Python example using the `pandas` library for ETL:


```python

import pandas as pd


# Extract data from a CSV file

data = pd.read_csv("source_data.csv")


# Transform data (e.g., clean, filter, aggregate)

transformed_data = data.dropna()  # Drop rows with missing values


# Load transformed data into a new CSV file

transformed_data.to_csv("transformed_data.csv", index=False)

```


This example reads data from a CSV file, applies a transformation to remove rows with missing values, and then saves the transformed data to a new CSV file.


Deep Dive with Databricks and Azure Data Lake Storage (ADLS Gen2):


Databricks is a unified analytics platform that integrates with Azure services like Azure Data Lake Storage Gen2 (ADLS Gen2) for building and deploying big data and machine learning applications. 

Here's a high-level overview of using Databricks and ADLS Gen2 for ETL:


1. Data Ingestion: Ingest data from various sources into ADLS Gen2 using Azure Data Factory, Azure Event Hubs, or other data ingestion tools.

2. ETL Processing: Use Databricks notebooks to perform ETL processing on the data stored in ADLS Gen2. Databricks provides a distributed computing environment for processing large datasets using Apache Spark.

3. Data Loading: After processing, load the transformed data back into ADLS Gen2 or other target destinations for further analysis or reporting.


Here's a simplified example of ETL processing with Databricks and ADLS Gen2 using Python Pyspark:


```python

from pyspark.sql import SparkSession


# Initialize Spark session

spark = SparkSession.builder \

    .appName("ETL Example") \

    .getOrCreate()


# Read data from ADLS Gen2

df = spark.read.csv("adl://


account_name.dfs.core.windows.net/path/to/source_data.csv", header=True)


# Perform transformations

transformed_df = df.dropna()


# Write transformed data back to ADLS Gen2

transformed_df.write.csv("adl://account_name.dfs.core.windows.net/path/to/transformed_data", mode="overwrite")


# Stop Spark session

spark.stop()

```


In this example, we use the `pyspark` library to read data from ADLS Gen2, perform a transformation to drop null values, and then write the transformed data back to ADLS Gen2.


This is a simplified illustration of ETL processing with Python, Databricks, and ADLS Gen2. In a real-world scenario, you would handle more complex transformations, error handling, monitoring, and scaling considerations. Additionally, you might leverage other Azure services such as Azure Data Factory for orchestration and Azure Synapse Analytics for data warehousing and analytics.

Data Masking When Ingesting Into Databricks

 

Photo by Alba Leader

Data masking is a data security technique that involves hiding data by changing its original numbers and letters. It's a way to create a fake version of data that's similar enough to the actual data, while still protecting it. This fake data can then be used as a functional alternative when the real data isn't needed. 



Unity Catalog is not a feature within Databricks. Instead, Databricks provides the Delta Lake feature, which includes data governance capabilities such as row filters and column masking.

Unity Catalog in Databricks allows you to apply data governance policies such as row filters and column masks to sensitive data. Let’s break it down:

  1. Row Filters:

    • Row filters enable you to apply a filter to a table so that subsequent queries only return rows for which the filter predicate evaluates to true.
    • To create a row filter, follow these steps:
      1. Write a SQL user-defined function (UDF) to define the filter policy.
      • CREATE FUNCTION <function_name> (<parametergoog_1380099708_name> <parameter_type>, ...) RETURN {filter clause whobe a boolean};
  2. Apply the row filter to an existing table using the following syntax:
    ALTER TABLE <table_name> SET ROW FILTER <function_name> ON (<column_name>, ...);
      1. You can also specify a row filter during the initial table creation.
    • Each table can have only one row filter, and it accepts input parameters that bind to specific columns of the table.
  3. Column Masks:

    • Column masks allow you to transform or mask specific column values before returning them in query results.
    • To apply column masks:
      1. Create a function that defines the masking logic.
      2. Apply the masking function to a table column using an ALTER TABLE statement.
      3. Alternatively, you can apply the masking function during table creation.
  4. Unity Catalog Best Practices:

  5. When setting up Unity Catalog, consider assigning a location to a catalog level. For example:
    CREATE CATALOG hr_prod
    LOCATION 'abfss://mycompany-hr-prod@storage-account.dfs.core.windows.net/unity-catalog';

You can apply column masks to transform or conceal specific column values before returning them in query results. Here’s how you can achieve this:

  1. Create a Masking Function:

    • Define a function that specifies the masking logic. This function will be used to transform the column values.
    • For example, let’s say you want to mask the last four digits of a credit card number. You can create a masking function that replaces the last four digits with asterisks.
  2. Apply the Masking Function to a Column:

    • Use an ALTER TABLE statement to apply the masking function to a specific column.
    • For instance, if you have a column named credit_card_number, you can apply the masking function to it:
      ALTER TABLE my_table SET COLUMN MASK credit_card_number USING my_masking_function;
      
  3. Example Masking Function:

    • Suppose you want to mask the last four digits of a credit card number with asterisks. You can create a masking function like this:
      CREATE FUNCTION my_masking_function AS
      BEGIN
          RETURN CONCAT('************', RIGHT(credit_card_number, 4));
      END;
      
  4. Query the Table:

    • When querying the table, the masked values will be returned instead of the original values.

Let’s focus on how you can achieve column masking in Databricks using Delta Lake:

  1. Column Masking:

    • Delta Lake allows you to apply column-level transformations or masks to sensitive data.
    • You can create custom masking functions to modify specific column values before returning them in query results.
  2. Creating a Masking Function:

    • Define a user-defined function (UDF) that specifies the masking logic. For example, you can create a function that masks the last four digits of a credit card number.
    • Here’s an example of a masking function that replaces the last four digits with asterisks:
      def mask_credit_card(card_number):
          return "************" + card_number[-4:]
      
  3. Applying the Masking Function:

    • Use the withColumn method to apply the masking function to a specific column in your DataFrame.
    • For instance, if you have a DataFrame named my_table with a column named credit_card_number, you can apply the masking function as follows:
      from pyspark.sql.functions import udf
      from pyspark.sql.types import StringType
      
      # Register the UDF
      spark.udf.register("mask_credit_card", mask_credit_card, StringType())
      
      # Apply the masking function to the column
      masked_df = my_table.withColumn("masked_credit_card", udf("credit_card_number"))
      
  4. Querying the Masked Data:

    • When querying the masked_df, the transformed (masked) values will be returned for the masked_credit_card column.

Sure, below is a simplified implementation example of the backend serverless function using Lambda, FastAPI, Kafka, and Protocol Buffers for the given application:

python code

# Lambda function handler

import json

from fastapi import FastAPI

from kafka import KafkaProducer

from pydantic import BaseModel


app = FastAPI()


class EggScan(BaseModel):

    egg_id: str

    scan_data: bytes


@app.post("/process-egg-scan")

async def process_egg_scan(egg_scan: EggScan):

    # Send egg scan data to Kafka topic

    producer = KafkaProducer(bootstrap_servers='your_kafka_broker:9092')

    producer.send('egg-scans', egg_scan.json().encode('utf-8'))

    producer.flush()

    

    return {"message": "Egg scan data processed successfully"}


# Kafka consumer handler

from kafka import KafkaConsumer

from fastapi import BackgroundTasks

from typing import Dict


async def process_egg_scan_background(egg_scan: Dict):

    # Implement your processing logic here

    print("Processing egg scan:", egg_scan)


@app.on_event("startup")

async def startup_event():

    # Start Kafka consumer

    consumer = KafkaConsumer('egg-scans', bootstrap_servers='your_kafka_broker:9092', group_id='egg-processing-group')

    for message in consumer:

        egg_scan = json.loads(message.value.decode('utf-8'))

        # Execute processing logic in background

        background_tasks.add_task(process_egg_scan_background, egg_scan)


# Protocol Buffers implementation (protobuf files and code generation)

# Example protobuf definition (egg_scan.proto)

"""

syntax = "proto3";


message EggScan {

  string egg_id = 1;

  bytes scan_data = 2;

}

"""


# Compile protobuf definition to Python code

# protoc -I=. --python_out=. egg_scan.proto


# Generated Python code usage

from egg_scan_pb2 import EggScan


egg_scan = EggScan()

egg_scan.egg_id = "123"

egg_scan.scan_data = b"example_scan_data"


# Serialize to bytes

egg_scan_bytes = egg_scan.SerializeToString()


# Deserialize from bytes

deserialized_egg_scan = EggScan()

deserialized_egg_scan.ParseFromString(egg_scan_bytes)

In this example:

The FastAPI application receives egg scan data via HTTP POST requests at the /process-egg-scan endpoint. Upon receiving the data, it sends it to a Kafka topic named 'egg-scans'.

The Kafka consumer runs asynchronously on the FastAPI server using BackgroundTasks. It consumes messages from the 'egg-scans' topic and processes them in the background.

Protocol Buffers are used for serializing and deserializing the egg scan data efficiently.

Please note that this is a simplified example for demonstration purposes. In a production environment, you would need to handle error cases, implement proper serialization/deserialization, configure Kafka for production use, handle scaling and concurrency issues, and ensure proper security measures are in place.

Below are simplified examples of worker process scripts for two microservices: one for processing and saving data, and another for serving customer/admin requests related to the data.

Microservice 1: Processing and Saving Data

```python

# worker_process.py


from kafka import KafkaConsumer

from pymongo import MongoClient

from egg_scan_pb2 import EggScan


# Kafka consumer configuration

consumer = KafkaConsumer('egg-scans', bootstrap_servers='your_kafka_broker:9092', group_id='egg-processing-group')


# MongoDB client initialization

mongo_client = MongoClient('mongodb://your_mongodb_uri')

db = mongo_client['egg_scans_db']

egg_scans_collection = db['egg_scans']


# Processing and saving logic

for message in consumer:

    egg_scan = EggScan()

    egg_scan.ParseFromString(message.value)

    

    # Process egg scan data

    processed_data = process_egg_scan(egg_scan)

    

    # Save processed data to MongoDB

    egg_scans_collection.insert_one(processed_data)

```


Microservice 2: Serving Customer/Admin Requests

```python

# data_service.py


from fastapi import FastAPI

from pymongo import MongoClient


app = FastAPI()


# MongoDB client initialization

mongo_client = MongoClient('mongodb://your_mongodb_uri')

db = mongo_client['egg_scans_db']

egg_scans_collection = db['egg_scans']


@app.get("/egg-scans/{egg_id}")

async def get_egg_scan(egg_id: str):

    # Retrieve egg scan data from MongoDB

    egg_scan_data = egg_scans_collection.find_one({"egg_id": egg_id})

    if egg_scan_data:

        return egg_scan_data

    else:

        return {"message": "Egg scan data not found"}


@app.get("/egg-scans")

async def get_all_egg_scans():

    # Retrieve all egg scan data from MongoDB

    all_egg_scans = egg_scans_collection.find()

    return list(all_egg_scans)

```

In these examples:

- Microservice 1 (`worker_process.py`) listens to the Kafka topic `'egg-scans'`, processes incoming egg scan data, and saves the processed data to a MongoDB database.

- Microservice 2 (`data_service.py`) is a FastAPI application that provides HTTP endpoints for retrieving egg scan data from MongoDB. It has two endpoints: one for retrieving data for a specific egg ID (`/egg-scans/{egg_id}`) and another for retrieving all egg scan data (`/egg-scans`).

These scripts are simplified for demonstration purposes. In a production environment, you would need to handle error cases, implement proper logging, configure authentication and authorization, and consider scalability and performance optimizations. Additionally, you may want to deploy these microservices in containers for easier management and scalability.

Hope this gives you an idea to start thinking of real solutions. Below are some reference links.
