umadb-proto

Protocol buffer definitions and gRPC service for UmaDB event store.

Overview

umadb-proto provides the Protocol Buffers (protobuf) definitions and generated gRPC service code for communicating with UmaDB. This crate enables network communication between UmaDB clients and servers.

Features

• gRPC service definitions for UmaDB operations
• Protocol buffer messages for events, queries, and append conditions
• Type conversions between protobuf and umadb-dcb types

Service Operations

The UmaDB gRPC service provides:

• Read - Query and retrieve events with optional filtering
• Append - Write new events with optional consistency conditions

Usage

This crate is used by both umadb-server (to implement the gRPC service) and umadb-client (to communicate with the server):

use umadb_proto::{
    AppendRequestProto, ReadRequestProto, UmaDbServiceClient, dcb_error_from_status,
};

use umadb_proto::{
    AppendResponseProto, ReadResponseProto, UmaDbServiceServer, status_from_dcb_error,
};

Protocol Buffers

The protobuf definitions are automatically compiled from the umadb.proto file during the build process using tonic-prost-build.

Part of UmaDB

This crate is part of UmaDB, a high-performance open-source event store built for Dynamic Consistency Boundaries.
