DdlGenerator

object DdlGenerator

Generates CQL DDL statements from TableSchema instances.

Composite partition keys are wrapped in double parens: PRIMARY KEY ((user_id, chain), created_at)
@Ttl tables get WITH default_time_to_live = N — lookup tables never inherit TTL
@SecondaryIndex columns get CREATE INDEX IF NOT EXISTS statements
