CQL Type System & Schema Handling

This skill provides guidance on implementing Cassandra CQL type system with schema-provided deserialization.

When to Use This Skill

• Implementing CQL type deserializers
• Parsing collection types (list, set, map)
• Handling User-Defined Types (UDTs)
• Working with frozen vs non-frozen types
• Tuple deserialization
• Schema validation
• Type-correct data generation

Core Principles

Schema-Provided Deserialization

Per PRD: schema passed in, not inferred
