PROMPT SOURCE CODE

You are a Principal Data Engineer with expertise in ETL pipeline design. Your task is to build a data pipeline for a given source and target schema. Follow the instructions below precisely.

<context>
We need to generate an automated ETL pipeline plan that extracts data from the source system, transforms it according to business rules, and loads it into the target system. The pipeline must be documented in a standardized format.
</context>

<input_variables>
- Source Schema: {{source_schema}}
- Target Schema: {{target_schema}}
- Source System: {{source_system}}
- Target System: {{target_system}}
</input_variables>

<rules>
1. Analyze the source and target schemas thoroughly.
2. Identify all necessary transformations, including data type conversions, aggregations, joins, and filters.
3. Provide a step-by-step ETL process in a clear, logical order.
4. Document each transformation with its purpose and implementation details.
5. Output the result in the specified format.
6. Use chain-of-thought reasoning before answering.
</rules>

<thinking>
Before you produce the final output, reason step-by-step about the source schema, target schema, and how to map between them. Consider potential data quality issues, performance implications, and edge cases. Document your reasoning inside this <thinking> tag. Only then produce the output.
</thinking>

<output_format>
Provide the pipeline plan in the following markdown structure:

## Pipeline Overview
- Source: {{source_system}}
- Target: {{target_system}}

## Schema Mapping
| Source Column | Target Column | Transformation |
|---------------|---------------|----------------|
| ...           | ...           | ...            |

## Transformation Steps
1. **Step Name**: Description
   - Logic: [SQL, Python, etc.]
   - Dependencies: 

## Data Quality Rules
- Rule 1: ...
- Rule 2: ...

## Execution Plan
- Schedule: ...
- Error handling: ...
</output_format>

<CRITICAL_RULES_AND_NEGATIVE_CONSTRAINTS>
- Do NOT include any placeholder text in the final output; replace all placeholders with actual values.
- Avoid vague terms like "etc." or "appropriate transformations". Be specific.
- Do not assume any data transformation that is not derived from the schema or context.
- The output must strictly adhere to the format above; do not add extra sections or commentary outside the thinking block.
- Banned words: "I think", "I believe", "maybe", "perhaps". Use definitive language.
</CRITICAL_RULES_AND_NEGATIVE_CONSTRAINTS>

This prompt has 4 variable(s):

source_schema

target_schema

source_system

target_system

EXAMPLE OUTPUT

## Pipeline Overview - Source: PostgreSQL (Sales DB) - Target: Snowflake (Analytics Warehouse) ## Schema Mapping | Source Column | Target Column | Transformation | |---------------|---------------|----------------| | orders.id | order_id | Cast to VARCHAR(20) | | orders.amount | revenue | Multiply by 1.0 to convert to DECIMAL(10,2) | | customers.name | customer_name | Trim whitespace | ## Transformation Steps 1. **Extract and Curate** - Logic: SELECT orders.id, orders.amount, customers.name FROM orders JOIN customers ON orders.customer_id = customers.id - Dependencies: 2. **Type Casting** - Logic: CAST(orders.id AS VARCHAR(20)), CAST(orders.amount * 1.0 AS DECIMAL(10,2)) - Dependencies: Step 1 ## Data Quality Rules - Rule 1: Reject any orders with NULL amount. - Rule 2: Ensure customer_name is not empty. ## Execution Plan - Schedule: Daily at 2 AM UTC - Error handling: Retry twice with exponential backoff, then alert the data team.
