Vald Update APIs

Overview

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

Update RPC is the method to update a single vector.

Input

  • the scheme of payload.v1.Update.Request

    message Update {
      message Request {
          Object.Vector vector = 1 [ (validate.rules).repeated .min_items = 2 ];
          Config config = 2;
      }
    
      message Config {
          bool skip_strict_exist_check = 1;
          Filter.Config filters = 2;
          int64 timestamp = 3;
      }
    }
    
    message Object {
        message Vector {
            string id = 1 [ (validate.rules).string.min_len = 1 ];
            repeated float vector = 2 [ (validate.rules).repeated.min_items = 2 ];
        }

StreamUpdate RPC

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.

Input

  • the scheme of payload.v1.Update.Request stream

    message Update {
        message Request {
            Object.Vector vector = 1 [ (validate.rules).repeated .min_items = 2 ];
            Config config = 2;
        }
        message Config {
            bool skip_strict_exist_check = 1;
            Filter.Config filters = 2;
            int64 timestamp = 3;
        }
    }
    
    message Object {
        message Vector {
            string id = 1 [ (validate.rules).string.min_len = 1 ];
            repeated float vector = 2 [ (validate.rules).repeated .min_items = 2 ];
        }

MultiUpdate RPC

MultiUpdate is the method to update multiple vectors in 1 request.

gRPC has the message size limitation.
Please be careful that the size of the request exceed the limit.

Input

  • the scheme of payload.v1.Update.MultiRequest

    message Update {
        message MultiRequest { repeated Request requests = 1; }
    
        message Request {
            Object.Vector vector = 1 [ (validate.rules).repeated .min_items = 2 ];
            Config config = 2;
        }
    
        message Config {
            bool skip_strict_exist_check = 1;
            Filter.Config filters = 2;
            int64 timestamp = 3;
        }
    }
    
    message Object {
        message Vector {
            string id = 1 [ (validate.rules).string.min_len = 1 ];
            repeated float vector = 2 [ (validate.rules).repeated .min_items = 2 ];
