odibi 2.9.0

A declarative data engineering framework - Explicit over implicit, Stories over magic

Odibi

Declarative data pipelines. YAML in, star schemas out.

Odibi is a framework for building data pipelines. You describe what you want in YAML; Odibi handles how. Every run generates a "Data Story" — an audit report showing exactly what happened to your data.

🤖 AI/LLM Users: For comprehensive context, see docs/ODIBI_DEEP_CONTEXT.md — 2,200+ lines covering all patterns, transformers, validation, connections, and runtime behavior.

⚡ Quick Start

pip install odibi

Option 1: Start from a template

odibi init my_project --template star-schema
cd my_project
odibi run odibi.yaml
odibi story last          # View the audit report

Option 2: Clone the reference example

git clone https://github.com/henryodibi11/Odibi.git
cd Odibi/docs/examples/canonical/runnable
odibi run 04_fact_table.yaml

This builds a complete star schema in seconds:

• 3 dimension tables (customer, product, date)
• 1 fact table with FK lookups and orphan handling
• HTML audit report

📖 The Canonical Example

pipelines:
  - pipeline: build_dimensions
    nodes:
      - name: dim_customer
        read:
          connection: source
          format: csv
          path: customers.csv
        pattern:
          type: dimension
          params:
            natural_key: customer_id
            surrogate_key: customer_sk
            scd_type: 1
        write:
          connection: gold
          format: parquet
          path: dim_customer

      - name: dim_date
        pattern:
          type: date_dimension
          params:
            start_date: "2025-01-01"
            end_date: "2025-12-31"
        write:
          connection: gold
          format: parquet
          path: dim_date

  - pipeline: build_facts
    nodes:
      - name: fact_sales
        depends_on: [dim_customer, dim_date]
        read:
          connection: source
          format: csv
          path: orders.csv
        pattern:
          type: fact
          params:
            grain: [order_id, line_item_id]
            dimensions:
              - source_column: customer_id
                dimension_table: dim_customer
                dimension_key: customer_id
                surrogate_key: customer_sk
            orphan_handling: unknown
        write:
          connection: gold
          format: parquet
          path: fact_sales
