Exam Domains

Domain 1: Data Movement (25-30%)

  • Snowpipe continuous loading architecture
  • Snowpipe Streaming for low-latency ingestion
  • Bulk data loading with COPY INTO
  • External stages and storage integrations
  • Data unloading and export patterns
  • Connector ecosystem (Kafka, Spark)

Key Concepts: - Snowpipe auto-ingest with cloud event notifications - Snowpipe Streaming via Ingest SDK (row-level API) - Stage types: internal, external (S3, Azure Blob, GCS) - File format options and error handling - COPY INTO options and transformations during load - Kafka connector with Snowpipe Streaming mode

Domain 2: Data Pipelines and Transformations (25-30%)

  • Tasks and DAG orchestration
  • Streams for change data capture (CDC)
  • Dynamic tables for declarative pipelines
  • Snowpark for programmatic transformations
  • UDFs and stored procedures
  • Error handling and pipeline monitoring

Key Concepts: - Task trees (DAGs) with dependencies and scheduling - Stream types: standard, append-only, insert-only - Dynamic table target lag and refresh mechanics - Snowpark DataFrame API for complex transformations - Python, Java, and Scala UDF development - TASK_HISTORY and PIPE_USAGE_HISTORY monitoring

Domain 3: Performance and Optimization (20-25%)

  • Warehouse sizing for data engineering workloads
  • Clustering strategies for pipeline output tables
  • Query optimization for transformation queries
  • Materialized views vs dynamic tables
  • Cost management for pipeline operations

Key Concepts: - Warehouse sizing for COPY INTO vs transformation queries - Clustering key selection for downstream query patterns - Pruning optimization in pipeline queries - Resource monitors for pipeline cost control - Serverless task credit management

Domain 4: Data Governance and Security (15-20%)

  • Role-based access control for pipeline objects
  • Dynamic data masking in pipeline outputs
  • Object tagging for pipeline data classification
  • Audit and compliance for data movement
  • Secure data sharing of pipeline outputs

Key Concepts: - Granting privileges on tasks, streams, and pipes - Masking policies applied during transformation - Tag propagation through pipeline stages - ACCESS_HISTORY for audit trails - Secure views for sharing transformed data

Key Study Areas

Data Ingestion Patterns

  • Snowpipe: Event-driven continuous loading from cloud storage
  • Snowpipe Streaming: Row-level API-based ingestion for real-time
  • COPY INTO: Bulk loading with transformation capabilities
  • Kafka Connector: Streaming from Kafka topics to Snowflake
  • External Tables: Query data in place without loading

Pipeline Orchestration

  • Tasks: Scheduled or event-driven SQL/procedure execution
  • Streams: Change tracking on tables for CDC patterns
  • Dynamic Tables: Declarative pipelines with target lag
  • Snowpark: Programmatic pipeline logic in Python/Java/Scala

Transformation Capabilities

  • SQL Transformations: Views, CTEs, window functions
  • Snowpark DataFrame: Programmatic transformation chains
  • UDFs: Custom scalar and table functions
  • Stored Procedures: Complex multi-step pipeline logic
  • External Functions: Integration with external services

Hands-On Skills Required

Pipeline Development

  • Design and implement Snowpipe auto-ingest pipelines
