Collect raw data from multiple sources and ingest it securely into cloud storage with proper validation and monitoring.

1.1 Generate Sample Data (1-2 hrs)

python step1-data-ingestion\data_generator.py

Creates:

• data/raw/vendora/, vendorb/, etc. - Vendor shipment files (CSV)
• vehicle_telemetry_*.csv - GPS, speed, fuel, sensor data
• weather_data_*.csv - Weather conditions by city
• currency_rates_*.csv - Exchange rates
• delivery_performance_*.csv - Historical delivery data

1.2 Setup Cloud Storage (2-3 hrs)

AWS S3:

aws s3 mb s3://logistics-raw-data
aws s3api put-bucket-encryption --bucket logistics-raw-data --server-side-encryption-configuration '{\"Rules\":[{\"ApplyServerSideEncryptionByDefault\":{\"SSEAlgorithm\":\"AES256\"}}]}'

Azure:

az storage account create --name logisticsstorage --resource-group logistics-rg
az storage container create --name raw-data --account-name logisticsstorage

GCP:

gsutil mb gs://logistics-raw-data
gsutil versioning set on gs://logistics-raw-data

1.3 Configure Credentials Edit config/config.json with your cloud details, then set environment variables.

1.4 Run Batch Ingestion (15-20 hrs)

python step1-data-ingestion\batch_ingestion.py

What happens:

• Reads files from data/raw/
• Validates schema (checks required columns)
• Calculates MD5 checksum
• Uploads to cloud with partitioning: staging/vendor=X/year=2026/month=01/day=20/
• Creates manifest JSON with file metadata
• Logs success/failures

Test: Check cloud storage console - you should see partitioned folders with your data files.

1.5 Optional: Streaming Ingestion (10-15 hrs)

# Start Kafka
docker-compose up -d kafka zookeeper

# Produce streaming data
python step1-data-ingestion\streaming_ingestion.py

What happens:

• Simulates real-time vehicle telemetry
• Sends messages to Kafka topic logistics-events
• You can consume these for real-time processing

✅ Raw data files in cloud storage (S3/ADLS/GCS)
✅ Ingestion manifest file (data/ingestion_manifest.json)
✅ Logs showing successful uploads
✅ Data partitioned by vendor/year/month/day

Transform raw data into clean, enriched, analytics-ready format using Apache Spark.

2.1 Install Spark (Local) or Setup Cloud Cluster (5-8 hrs)

Local (for testing):

pip install pyspark

AWS EMR (production):

aws emr create-cluster \
  --name "Logistics-ETL-Cluster" \
  --release-label emr-6.10.0 \
  --applications Name=Spark Name=Hadoop \
  --instance-type m5.xlarge \
  --instance-count 3 \
  --use-default-roles

Azure Databricks:

• Create workspace in Azure Portal
• Create cluster (Standard_DS3_v2, 2-8 workers)

GCP Dataproc:

gcloud dataproc clusters create logistics-cluster \
  --region us-central1 \
  --num-workers 2

2.2 Run Spark ETL Pipeline (20-25 hrs)

# Local
spark-submit step2-data-processing\spark_etl_pipeline.py

# EMR
aws emr add-steps --cluster-id j-XXXXX \
  --steps Type=Spark,Name="ETL",ActionOnFailure=CONTINUE,Args=[step2-data-processing/spark_etl_pipeline.py]

What the pipeline does:

A. Read Raw Data

• Loads CSV files from cloud staging zone
• Infers or applies schema

B. Data Cleansing

• Duplicates: Removes exact duplicate rows
• Missing Values:
  • Drops rows with missing critical fields (shipment_id, vendor_id)
  • Fills numeric nulls with median
  • Fills text nulls with 'Unknown'
• Type Casting: Converts dates, numbers to proper types
• Standardization: Uppercases text, trims whitespace

C. Feature Engineering

• avg_speed_kmh = distance_km / estimated_delivery_hours
• fuel_efficiency = distance_km / fuel_consumed
• route_time_category = Short/Medium/Long/Very Long
• year, month, day = Extract from shipment_date

D. External Enrichment

• Joins weather data (by city + date)
• Joins currency rates (by date)
• Adds temperature, humidity, wind to each shipment

E. Write Processed Data

df.write \
  .partitionBy("vendor_id", "year", "month") \
  .mode("overwrite") \
  .parquet("s3://logistics-processed/shipments/")

• Format: Parquet (columnar, compressed)
• Compression: Snappy
• Partitioning: By vendor, year, month (for efficient queries)

F. Data Quality Report

• Generates report showing:
  • Total records per column
  • Null counts and percentages
  • Distinct value counts

2.3 Register in Data Catalog (5-8 hrs)

AWS Athena:

CREATE EXTERNAL TABLE processed_shipments (
  shipment_id STRING,
  vendor_id STRING,
  distance_km DOUBLE,
  avg_speed_kmh DOUBLE,
  temperature_c DOUBLE,
  ...
)
PARTITIONED BY (vendor_id STRING, year INT, month INT)
STORED AS PARQUET
LOCATION 's3://logistics-processed/shipments/';

-- Add partitions
MSCK REPAIR TABLE processed_shipments;

-- Query
SELECT vendor_id, COUNT(*) FROM processed_shipments GROUP BY vendor_id;

Azure Synapse:

CREATE EXTERNAL TABLE processed_shipments
WITH (
    LOCATION = '/processed/shipments/',
    DATA_SOURCE = logistics_storage,
    FILE_FORMAT = PARQUET_FORMAT
)
AS SELECT * FROM ...;

GCP BigQuery:

bq mk --external_table_definition=gs://logistics-processed/shipments/*::PARQUET \
  logistics:processed_shipments

2.4 Validate Data Quality (5 hrs)

-- Check record counts
SELECT COUNT(*) FROM processed_shipments;

-- Check for nulls in critical columns
SELECT COUNT(*) FROM processed_shipments WHERE shipment_id IS NULL;

-- Verify partitioning
SELECT vendor_id, year, month, COUNT(*) 
FROM processed_shipments 
GROUP BY vendor_id, year, month;

✅ Processed data in Parquet format in cloud storage
✅ Data partitioned by vendor, year, month
✅ Data quality report generated
✅ Tables registered and queryable in Athena/BigQuery/Synapse

Build machine learning models for predictions and create interactive dashboards.

3.1 Train ML Models (15-20 hrs)

spark-submit step3-analytics-ml\predictive_analytics.py

Model 1: Delivery Delay Predictor

• Goal: Predict how many minutes a delivery will be delayed
• Algorithm: Random Forest Regression
• Features: distance_km, package_weight_kg, avg_speed_kmh, temperature_c, humidity, wind_speed
• Output: Predicted delay in minutes
• Evaluation:
  • RMSE (Root Mean Squared Error) - lower is better
  • MAE (Mean Absolute Error)
  • R² score - closer to 1.0 is better

Model 2: Anomaly Detection

• Goal: Flag vehicles with unusual sensor readings (potential issues)
• Algorithm: Random Forest Classifier
• Features: speed_kmh, engine_temperature_c, fuel_level, tire_pressure, battery_voltage
• Output: 0 (normal) or 1 (anomaly)
• Rules: Anomaly if speed >120, engine temp >105, tire pressure <28, fuel <10%
• Evaluation:
  • AUC (Area Under ROC Curve) - higher is better
  • Accuracy, Precision, Recall

Model 3: Predictive Maintenance

• Goal: Score vehicles 0-1 on maintenance need
• Algorithm: Gradient Boosted Trees Regressor
• Features: odometer_km, engine_temperature, tire_pressure, battery_voltage
• Output: Maintenance score (0.0 = good, 1.0 = needs service)

What happens:

• Trains on 80% of data, tests on 20%
• Saves models to models/delay_predictor/, anomaly_detector/, maintenance_predictor/
• Generates predictions and saves to data/analytics/

3.2 Evaluate Models (5 hrs) Check the output logs for metrics:

Delay Predictor: RMSE=25.3 minutes, R²=0.85
Anomaly Detector: AUC=0.92, Accuracy=0.89

Good performance indicators:

• Delay: RMSE <30 min, R² >0.80
• Anomaly: AUC >0.85
• Maintenance: Scores align with actual failures

3.3 Create BI Views (5 hrs)

View 1: Real-Time Fleet Status

CREATE VIEW fleet_status AS
SELECT 
  vehicle_id,
  latitude,
  longitude,
  speed_kmh,
  fuel_level_percent,
  maintenance_score,
  CASE WHEN maintenance_score > 0.7 THEN 'High'
       WHEN maintenance_score > 0.4 THEN 'Medium'
       ELSE 'Low' END AS maintenance_priority,
  timestamp
FROM vehicle_telemetry t
JOIN maintenance_predictions p ON t.vehicle_id = p.vehicle_id
WHERE status = 'Active';

View 2: Delivery KPIs

CREATE VIEW delivery_kpis AS
SELECT 
  vendor_id,
  COUNT(*) AS total_deliveries,
  AVG(delay_minutes) AS avg_delay,
  SUM(CASE WHEN on_time = 'Yes' THEN 1 ELSE 0 END) * 100.0 / COUNT(*) AS on_time_percent,
  AVG(customer_rating) AS avg_rating
FROM delivery_performance
GROUP BY vendor_id;

3.4 Build Dashboards (5-10 hrs)

Power BI:

1. Open Power BI Desktop
2. Get Data → More → Amazon Athena / Azure Synapse / BigQuery
3. Enter connection details
4. Import views: fleet_status, delivery_kpis, delay_predictions
