• Adds new attributes from model (with placeholders)
• Removes attributes no longer in the model
• Creates backups before overwriting

Available subcommands: mapping Merge mapping files with an updated model

Subcommands:

• daana-cli merge mapping

Examples:

# Merge a single mapping with updated model
daana-cli merge mapping --model model.yaml --mapping customer-mapping.yaml

# Merge all mappings in a workflow

Mapping

Synchronize mapping files with an updated model

Usage:

daana-cli merge mapping [flags]

Merge existing mapping files with an updated model while preserving customizations.

When to use:

• After adding new attributes to your model entities
• After changing attribute properties (e.g., effective_timestamp)
• After adding or removing relationships
• To ensure mappings reflect the latest model structure

What it preserves:

• Custom transformation expressions
• Table and connection configurations
• Where clauses and filters
• Ingestion strategies

What it updates:

• Adds new attributes from model (with placeholder transformations)
• Removes attributes no longer in model

• Atomic file writes (write to temp, then rename)
• Shows diff preview with --diff flag
• Dry-run mode with --dry-run flag

Modes: Single Mapping: --model and --mapping flags Workflow Mode: --workflow flag (merges all mappings in workflow)

Note: Model files can be YAML or JSON (YAML auto-compiles internally).

Flags:

Examples:

# Basic usage - merge and update in place (creates backup)
daana-cli merge mapping --model model.yaml --mapping customer-mapping.yaml

# Preview changes without writing files
daana-cli merge mapping --model model.yaml --mapping customer-mapping.yaml --diff

# See detailed verbose output during merge
daana-cli merge mapping --model model.yaml --mapping customer-mapping.yaml --verbose

# Dry run - see complete output without writing
daana-cli merge mapping --model model.yaml --mapping customer-mapping.yaml --dry-run

# Merge to a different output file
daana-cli merge mapping --model model.yaml --mapping customer-mapping.yaml --out merged.yaml

# Merge all mappings in a workflow
