A MilvusClient interface. This method shows the index building progress, such as how many rows are indexed.

R<GetIndexBuildProgressResponse> getIndexBuildProgress(GetIndexBuildProgressParam requestParam);


Use the GetIndexBuildProgressParam.Builder to construct a GetIndexBuildProgressParam object.

import io.milvus.param.GetIndexBuildProgressParam;
GetIndexBuildProgressParam.Builder builder = GetIndexBuildProgressParam.newBuilder();

Methods of GetIndexBuildProgressParam.Builder:

withCollectionName(collectionName)Sets the collection name. The collection name cannot be empty or null.collectionName: The name of the collection whose index building progress needs to be checked.
withIndexName(String indexName)Sets the target index name. The index name cannot be empty or null. If no index name is specified, the default index name _default_idx is used.indexName: The name of the index whose building progress needs to be checked.
build()Constructs a GetIndexBuildProgressParam object.N/A

The can throw the following exceptions:

  • ParamException: error if the parameter is invalid.


This method catches all the exceptions and returns an R<GetIndexBuildProgressResponse> object.

  • If the API fails on the server side, it returns the error code and message from the server.

  • If the API fails by RPC exception, it returns R.Status.Unknow and the error message of the exception.

  • If the API succeeds, it returns a valid GetIndexBuildProgressResponse held by the R template.
