Proto Message Design

Design Protocol Buffer message schemas with field numbers, cardinality, enums, nested messages, oneof groups, and map fields.

Protocol Buffer messages are the foundation of gRPC APIs. NeoArc's schema designer supports all proto3 features including field numbers, cardinality, nested messages, enums, oneof groups, map fields, and well-known types. Enable proto mode on any schema to access these features.

Scalar Types

Proto3 supports a rich set of scalar types for different data needs.
