Vehicles → Kafka → Databricks Streaming → Delta Lake
                           ↓
                    GPU Clusters (model training)
                           ↓
                  Model Serving (real-time inference)

When to Use Both​

The Lakehouse + Warehouse Pattern​

Common Architecture:

Raw Data → Databricks (ingestion, transformation, ML)
              ↓
         Delta Lake (single source of truth)
              ↓
    Aggregated Metrics → Snowflake (BI/reporting)
              ↓
    Tableau/Power BI Dashboards

Why This Works:

  • Databricks: Heavy lifting (ETL, feature engineering, ML training)
  • Snowflake: Serving layer (fast SQL queries, business user access)
  • Cost-effective: Use each platform for its strengths
  • Separation of concerns: Data engineers on Databricks, analysts on Snowflake

Sync Strategies:

  1. Delta Lake → Snowflake (nightly batch):

    • Databricks writes curated tables to S3 (Parquet)
    • Snowflake COPY INTO from S3 (scheduled via Airflow)

  2. Delta Lake → Snowflake (real-time):

    • Databricks Delta Sharing (direct query from Snowflake)
    • Or Databricks writes to Snowflake via JDBC

  3. Snowflake → Databricks (reverse sync):

    • Snowflake UNLOAD → S3 → Databricks reads (for ML training)

When NOT to Use Both​

Avoid dual-platform if:

  • Small team (<10 data professionals): Too much operational overhead
  • Simple use case: Pure SQL analytics → Snowflake only
  • Pure ML workload: No BI needs → Databricks only
  • Budget constraints: One platform license + cloud costs is enough
