Vald Update APIs

Overview

Update Service updates to new vector from inserted vector 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 ];
        }
    }

Troubleshooting

The request process may not be completed when the response code is NOT 0 (OK).

Here are some common reasons and how to resolve each error.

namecommon reasonhow to resolve
CANCELLEDExecuted cancel() of rpc from client/server-side or network problems between client and server.Check the code, especially around timeout and connection management, and fix if needed.
INVALID_ARGUMENTThe Dimension of the request vector is NOT the same as Vald Agent’s config, the requested vector’s ID is empty, or some request payload is invalid.Check Agent config, request payload, and fix request payload or Agent config.
DEADLINE_EXCEEDEDThe RPC timeout setting is too short on the client/server side.Check the gRPC timeout setting on both the client and server sides and fix it if needed.
NOT_FOUNDRequested ID is NOT inserted.Send a request with an ID that is already inserted.
ALREADY_EXISTSRequest pair of ID and vector is already inserted.Change request ID.
INTERNALTarget Vald cluster or network route has some critical error.Check target Vald cluster first and check network route including ingress as second.

StreamUpdate RPC

StreamUpdate RPC is the method to update multiple vectors using the bidirectional streaming RPC.
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 a message size limitation.
Please be careful that the size of the request exceeds 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 ];
