    LoadStateNotExist LoadState = 0
    LoadStateNotLoad  LoadState = 1
    LoadStateLoading  LoadState = 2
    LoadStateLoaded   LoadState = 3
)

  • ErrClientNotReady: The client is not connected to Milvus.

  • ErrCollectionNotExists: The collection with the specified name does not exist.

  • The call to this API fails.

Example​

errLoad := mc.LoadCollection(context.Background(), collectionName, true)
if errLoad != nil {
   log.Fatal("failed to load collection:", errLoad.Error())
}
// get load state
stateLoad, errState := mc.GetLoadState(context.Background(), collectionName, []string{})
if errState != nil {
   log.Fatal("failed to get load state:", errState.Error())
}
log.Println(stateLoad)
