Architecture Design\n- Assess: sources, volume, latency requirements, targets\n- Select pattern: ETL (transform before load), ELT (load then transform), Lambda (batch + speed layers), Kappa (stream-only), Lakehouse (unified)\n- Design flow: sources → ingestion → processing → storage → serving\n- Add observability touchpoints\n\n### 2. Ingestion Implementation\n**Batch**\n- Incremental loading with watermark columns\n- Retry logic with exponential backoff\n- Schema validation and dead letter queue for invalid records\n- Metadata tracking (_extracted_at, _source)\n\n**Streaming**\n- Kafka consumers with exactly-once semantics\n- Manual offset commits within transactions\n- Windowing for time-based aggregations\n- Error handling and replay capability\n\n### 3. Orchestration\n**Airflow**\n- Task groups for logical organization\n- XCom for inter-task communication\n- SLA monitoring and email alerts\n- Incremental execution with execution_date\n- Retry with exponential backoff\n\n**Prefect**\n- Task caching for idempotency\n- Parallel execution with .submit()\n- Artifacts for visibility\n- Automatic retries with configurable delays\n\n### 4. Transformation with dbt\n- Staging layer: incremental materialization, deduplication, late-arriving data handling\n- Marts layer: dimensional models, aggregations, business logic\n- Tests: unique, not_null, relationships, accepted_values, custom data quality tests\n- Sources: freshness checks, loaded_at_field tracking\n- Incremental strategy: merge or delete+insert\n\n### 5. Data Quality Framework\n**Great Expectations**\n- Table-level: row count, column count\n- Column-level: uniqueness, nullability, type validation, value sets, ranges\n- Checkpoints for validation execution\n- Data docs for documentation\n- Failure notifications\n\n**dbt Tests**\n- Schema tests in YAML\n- Custom data quality tests with dbt-expectations\n- Test results tracked in metadata\n\n### 6. Storage Strategy\n**Delta Lake**\n- ACID transactions with append\u002Foverwrite\u002Fmerge modes\n- Upsert with predicate-based matching\n- Time travel for historical queries\n- Optimize: compact small files, Z-order clustering\n- Vacuum to remove old files\n\n**Apache Iceberg**\n- Partitioning and sort order optimization\n- MERGE INTO for upserts\n- Snapshot isolation and time travel\n- File compaction with binpack strategy\n- Snapshot expiration for cleanup\n\n### 7. Monitoring & Cost Optimization\n**Monitoring**\n- Track: records processed\u002Ffailed, data size, execution time, success\u002Ffailure rates\n- CloudWatch metrics and custom namespaces\n- SNS alerts for critical\u002Fwarning\u002Finfo events\n- Data freshness checks\n- Performance trend analysis\n\n**Cost Optimization**\n- Partitioning: date\u002Fentity-based, avoid over-partitioning (keep >1GB)\n- File sizes: 512MB-1GB for Parquet\n- Lifecycle policies: hot (Standard) → warm (IA) → cold (Glacier)\n- Compute: spot instances for batch, on-demand for streaming, serverless for adhoc\n- Query optimization: partition pruning, clustering, predicate pushdown\n\n## Example: Minimal Batch Pipeline\n\n```python\n# Batch ingestion with validation\nfrom batch_ingestion import BatchDataIngester\nfrom storage.delta_lake_manager import DeltaLakeManager\nfrom data_quality.expectations_suite import DataQualityFramework\n\ningester = BatchDataIngester(config={})\n\n# Extract with incremental loading\ndf = ingester.extract_from_database(\n    connection_string='postgresql:\u002F\u002Fhost:5432\u002Fdb',\n    query='SELECT * FROM orders',\n    watermark_column='updated_at',\n    last_watermark=last_run_timestamp\n)\n\n# Validate\nschema = {'required_fields': ['id', 'user_id'], 'dtypes': {'id': 'int64'}}\ndf = ingester.validate_and_clean(df, schema)\n\n# Data quality checks\ndq = DataQualityFramework()\nresult = dq.validate_dataframe(df, suite_name='orders_suite', data_asset_name='orders')\n\n# Write to Delta Lake\ndelta_mgr = DeltaLakeManager(storage_path='s3:\u002F\u002Flake')\ndelta_mgr.create_or_update_table(\n    df=df,\n    table_name='orders',\n    partition_columns=['order_date'],\n    mode='append'\n)\n\n# Save failed records\ningester.save_dead_letter_queue('s3:\u002F\u002Flake\u002Fdlq\u002Forders')\n```\n\n## Output Deliverables\n\n### 1.
