Vald Insert APIs

Overview

Insert Service is responsible for inserting new vectors into the vald-agent.

service Insert {
    rpc Insert(payload.v1.Insert.Request) returns (payload.v1.Object.Location) {}

    rpc StreamInsert(stream payload.v1.Insert.Request) returns (stream payload.v1.Object.Location) {}

    rpc MultiInsert(payload.v1.Insert.MultiRequest) returns (payload.v1.Object.Locations) {}
}

Insert RPC

Inset RPC is the method to add a new single vector.

Input

  • the scheme of payload.v1.Insert.Request

    message Insert {
        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 ];
        }

Please refer to Response Status Code for more details.

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.
ALREADY_EXISTSRequest ID 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.

StreamInsert RPC

StreamInsert RPC is the method to add new multiple vectors using the bidirectional streaming RPC.
Using the bidirectional streaming RPC, the insert request can be communicated in any order between client and server. Each Insert request and response are independent. It’s the recommended method to insert a large number of vectors.

Input

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

    message Insert {
        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 ];
        }
    }

MultiInsert RPC

MultiInsert RPC is the method to add multiple new 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.Insert.MultiRequest

    message Insert {
        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 ];
