I have the following schema in my .proto
file:
service MyService {
rpc GetItem (ItemQuery) returns (Item) {
}
}
message ItemQuery {
int id = 1;
}
message Item {
int id = 1;
string name = 2;
}
Now I want to add another rpc method to return multiple Items. Something like this:
rpc GetItems (ItemsQuery) returns (repeated Item) {
}
Is there a better way to do it than define an Items message?
Option 1 - Use stream:
rpc GetItems (ItemsQuery) returns (stream Item) {
}
Option 2 - Set a response message which will use a repeated object:
service MyService {
rpc GetItem (ItemQuery) returns (ItemResponse) {
}
}
message ItemQuery {
int id = 1;
}
message ItemResponse {
repeated Item items = 1;
}
message Item {
int id = 1;
string name = 2;
}
