Cost Optimization

Example: Minimal Batch Pipeline

# Batch ingestion with validation
from batch_ingestion import BatchDataIngester
from storage.delta_lake_manager import DeltaLakeManager
from data_quality.expectations_suite import DataQualityFramework
ingester = BatchDataIngester(config={})
Extract with incremental loading

df = ingester.extract_from_database(
    connection_string='postgresql://host:5432/db',
    query='SELECT * FROM orders',
    watermark_column='updated_at',
    last_watermark=last_run_timestamp
)
Validate

schema = {'required_fields': ['id', 'user_id'], 'dtypes': {'id': 'int64'}}
df = ingester.validate_and_clean(df, schema)
Data quality checks

dq = DataQualityFramework()
result = dq.validate_dataframe(df, suite_name='orders_suite', data_asset_name='orders')
Write to Delta Lake

delta_mgr = DeltaLakeManager(storage_path='s3://lake')
delta_mgr.create_or_update_table(
    df=df,
    table_name='orders',
    partition_columns=['order_date'],
    mode='append'
)
Save failed records

ingester.save_dead_letter_queue('s3://lake/dlq/orders')
