What is Data Pipeline
Data Pipeline is an automated sequence of steps for extracting, processing, and delivering data from sources to target systems.
Pipeline Types
| Type | Description | Examples | |------|-------------|----------| | Batch | Scheduled batch processing | Daily reports | | Streaming | Real-time processing | IoT data, logs | | Hybrid | Batch and streaming combo | Lambda/Kappa architecture |
Pipeline Components
- Source — data sources (DB, API, files)
- Ingestion — loading into system
- Processing — transformations and enrichment
- Storage — storage (DWH, Data Lake)
- Serving — delivery to consumers
Popular Tools
| Category | Tools | |----------|-------| | Orchestration | Apache Airflow, Prefect, Dagster | | Streaming | Apache Kafka, Spark Streaming | | Batch | Apache Spark, dbt | | Cloud | AWS Glue, Azure Data Factory, GCP Dataflow |
Best Practices
- Idempotent operations
- Retry with exponential backoff
- Data lineage and monitoring
- Schema validation at ingestion
- Partitioning for performance
Error Handling Patterns
- Dead Letter Queue for failed records
- Circuit breaker for upstream systems
- Checkpointing for recovery
