Update Service is responsible for updating vectors which are already inserted in the vald-agent
components.
service Update {
rpc Update(payload.v1.Update.Request) returns (payload.v1.Object.Location) {}
rpc StreamUpdate(stream payload.v1.Update.Request) returns (stream payload.v1.Object.Location) {}
rpc MultiUpdate(payload.v1.Update.MultiRequest) returns (stream payload.v1.Object.Locations) {}
}
Update RPC is the method to update a single vector.

StreamUpdate RPC is the method to update multiple vectors using the bidirectional streaming RPC.
By using the bidirectional streaming RPC, the update request can be communicated in any order between client and server.
Each Update request and response are independent.
It's the recommended method to update the large amount of vectors.

MultiUpdate is the method to update multiple vectors in 1 request.
Please be careful that the size of the request exceed the limit.
