Schema Evolution Manager

Overview

Manages schema evolution and compatibility across data systems. This skill ensures safe schema changes that maintain backward and forward compatibility.

Capabilities

Schema compatibility checking (Avro, Protobuf, JSON Schema)
Breaking change detection
Migration script generation
Version management
Schema registry operations
Backward/forward compatibility validation
Schema documentation generation
Cross-system schema synchronization

Input Schema

{
  "currentSchema": "object",
  "proposedSchema": "object",
  "schemaFormat": "avro|protobuf|jsonschema|ddl",
  "compatibilityMode": "backward|forward|full|none"
}

Output Schema

{
  "compatible": "boolean",
  "breakingChanges": ["object"],
  "migrationScript": "string",
  "recommendations": ["string"],
  "versionInfo": "object"
}

Target Processes

Streaming Pipeline
ETL/ELT Pipeline
Data Catalog
Pipeline Migration

Usage Guidelines

Provide current and proposed schema definitions
Specify schema format for proper parsing
Define compatibility mode based on system requirements
Review breaking changes before proceeding with migration

Best Practices

Always test schema changes in non-production first
Use schema registry for centralized schema management
Document schema versions and changes
Plan migration strategies for breaking changes
Coordinate schema changes across dependent systems
