Modifiers

Overview

Field modifiers that control inheritance behavior in Cerial schemas.

Modifiers are keywords placed at the end of a field line that affect how the field behaves during schema inheritance. Unlike decorators (which use the @ prefix), modifiers use a different syntax and are processed at compile time.

@@unique

Create unique composite indexes spanning multiple fields for data integrity.

!!private
