unify-create-prep	Generate prep table creation files and configuration for ID unification

Create Prep Table Configuration

Overview

I'll generate prep table creation files and configuration using the dynamic-prep-creation specialized agent.

This command creates PRODUCTION-READY prep table files:

⚠️ EXACT TEMPLATES - No modifications allowed
⚠️ ZERO CHANGES - Character-for-character accuracy
✅ GENERIC FILES - Reusable across all projects
✅ DYNAMIC CONFIGURATION - Adapts to your table structure

What You Need to Provide

1. Table Analysis Results

If you've already run key extraction:

Provide the list of included tables with their user identifier columns
I can use the results from /cdp-unification:unify-extract-keys

OR provide directly:

Source tables: database.table_name format
User identifier columns: For each table, which columns contain identifiers

2. Client Configuration

Client short name: Your client identifier (e.g., mck, client_name)
Database suffixes:
- Source database suffix (default: src)
- Staging database suffix (default: stg)
- Lookup database (default: config)

3. Column Mappings

For each table, specify which columns to include and their unified aliases:

Email columns → alias: email
Phone columns → alias: phone
Customer ID columns → alias: customer_id
TD Client ID → alias: td_client_id
TD Global ID → alias: td_global_id

What I'll Do

Step 1: Create Directory Structure

I'll create:

unification/config/ directory
unification/queries/ directory

Step 2: Generate Generic Files (EXACT TEMPLATES)

I'll create these files with ZERO MODIFICATIONS:

⚠️ unification/dynmic_prep_creation.dig (EXACT filename - no 'a' in dynmic)

Generic prep workflow
Handles schema creation, table looping, and data insertion
Uses variables from config files

⚠️ unification/queries/create_schema.sql

Generic schema creation for unified input table
Creates both main and tmp tables

⚠️ unification/queries/loop_on_tables.sql

Complex production SQL for dynamic table processing
Generates prep table SQL and unified input table SQL
Handles incremental logic and deduplication

⚠️ unification/queries/unif_input_tbl.sql

DSAR processing and data cleaning
Exclusion list management for masked data
Dynamic column detection and insertion

Step 3: Generate Dynamic Configuration Files

unification/config/environment.yml

client_short_name: {your_client_name}
src: src
stg: stg
gld: gld
lkup: references

unification/config/src_prep_params.yml

Dynamic table configuration based on your table analysis
Column mappings with unified aliases
Prep table naming conventions

Step 4: Dynamic Column Detection (CRITICAL)

For unif_input_tbl.sql, I'll:

Query Treasure Data schema: information_schema.columns
Detect all columns besides email, phone, source, ingest_time, time
Auto-generate column list for data_cleaned CTE
Replace placeholder with actual columns

Expected Output

Generic Files (EXACT - NO CHANGES)

unification/
├── dynmic_prep_creation.dig          ⚠️ EXACT filename
├── queries/
│   ├── create_schema.sql             ⚠️ EXACT content
│   ├── loop_on_tables.sql            ⚠️ EXACT content
│   └── unif_input_tbl.sql            ⚠️ WITH dynamic columns

Dynamic Configuration Files

unification/config/
├── environment.yml                   ✓ Client-specific
└── src_prep_params.yml              ✓ Table-specific

Example src_prep_params.yml Structure

globals:
  unif_input_tbl: unif_input

prep_tbls:
  - src_tbl: user_events
    src_db: ${client_short_name}_${stg}
    snk_db: ${client_short_name}_${stg}
    snk_tbl: ${src_tbl}_prep
    columns:
      - col:
        name: user_email
        alias_as: email
      - col:
        name: td_client_id
        alias_as: td_client_id

  - src_tbl: customers
    src_db: ${client_short_name}_${stg}
    snk_db: ${client_short_name}_${stg}
    snk_tbl: ${src_tbl}_prep
    columns:
      - col:
        name: email
        alias_as: email
      - col:
        name: customer_id
        alias_as: customer_id

Critical Requirements

⚠️ NEVER MODIFY GENERIC FILES

dynmic_prep_creation.dig: EXACT template, character-for-character
create_schema.sql: EXACT SQL, no changes
loop_on_tables.sql: EXACT complex SQL, no modifications
unif_input_tbl.sql: EXACT template + dynamic column replacement

✅ DYNAMIC CONFIGURATION ONLY

environment.yml: Client-specific variables
src_prep_params.yml: Table-specific mappings

🚨 CRITICAL FILENAME

MUST be "dynmic_prep_creation.dig" (NO 'a' in dynmic)
This is intentional - production systems expect this exact name

🚨 NO TIME COLUMN

NEVER ADD time column to src_prep_params.yml
Time is auto-generated by SQL template
Only include actual identifier columns

Validation Checklist

Before completing, I'll verify:

File named "dynmic_prep_creation.dig" exists
Content matches template character-for-character
All variable placeholders preserved
Queries folder contains exact SQL files
Config folder contains YAML files
Dynamic columns inserted in unif_input_tbl.sql
No time column in src_prep_params.yml
All directories created

Success Criteria

All generated files will:

✅ EXACT TEMPLATES - Character-for-character accuracy
✅ PRODUCTION-READY - Deployable to TD without changes
✅ DYNAMIC CONFIGURATION - Adapts to table structure
✅ DSAR COMPLIANT - Includes exclusion list processing
✅ INCREMENTAL PROCESSING - Supports time-based updates

Next Steps

After prep creation, you can:

Test prep workflow: dig run unification/dynmic_prep_creation.dig
Create unification config: Use /cdp-unification:unify-create-config
Complete full setup: Use /cdp-unification:unify-setup

Getting Started

Ready to create prep tables? Please provide:

Table list with columns:

Table: analytics.user_events
Columns: user_email (email), td_client_id (td_client_id)

Table: crm.customers
Columns: email (email), customer_id (customer_id)

Client configuration:
```
Client short name: mck
```

I'll call the dynamic-prep-creation agent to generate all prep files with exact templates.

Let's create your prep table configuration!
