Gets replicate information from the Milvus cluster, such as the salvage checkpoint used after a force failover.

Go

func (c *Client) GetReplicateInfo(ctx context.Context, req *milvuspb.GetReplicateInfoRequest, opts ...grpc.CallOption) (*milvuspb.GetReplicateInfoResponse, error)

Request Syntax

Go

resp, err := cli.GetReplicateInfo(ctx, &milvuspb.GetReplicateInfoRequest{
	SourceClusterId: "source-cluster",
	TargetPchannel:  "source-channel-dml_0",
})

PARAMETERS:

• req (milvuspb.GetReplicateInfoRequest)

  The replicate-info request, with the following fields:

  • SourceClusterId (string) - The ID of the source cluster.
  • TargetPchannel (string) - The physical channel to query.

• opts (...grpc.CallOption)

  Optional gRPC call options.

RETURN TYPE:

*milvuspb.GetReplicateInfoResponse, error

RETURNS:

The replicate information of the requested source cluster and channel. Use resp.GetSalvageCheckpoint() to obtain the checkpoint from which to salvage unsynchronized messages after a force failover. Returns an error when the RPC fails.

ERROR HANDLING:

import (
	"context"

	"github.com/milvus-io/milvus-proto/go-api/v3/milvuspb"
	"github.com/milvus-io/milvus/client/v3/milvusclient"
)

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

cli, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
	Address: "127.0.0.1:19530",
})
if err != nil {
	// handle error
}
defer cli.Close(ctx)

resp, err := cli.GetReplicateInfo(ctx, &milvuspb.GetReplicateInfoRequest{
	SourceClusterId: "source-cluster",
	TargetPchannel:  "source-channel-dml_0",
})
if err != nil {
	// handle error
