getLoadStateV2()

This operation gets detailed load-state information for a collection or partition. Use it when you need both the current load state and loading progress.

public GetLoadStateResp getLoadStateV2(GetLoadStateReq request)

Request Syntax

getLoadStateV2(GetLoadStateReq.builder()
    .databaseName(String databaseName)

    .build());

BUILDER METHODS:

• databaseName(String databaseName)

  The database that contains the collection.

• collectionName(String collectionName)

  The collection whose load state is inspected.

• partitionName(String partitionName)

  An optional partition name. Omit it to inspect the collection-level load state.

RETURN TYPE:

GetLoadStateResp

RETURNS:

• getState() (LoadState) -

  The current load state of the collection or partition.

• getProgress() (Long) -

  The loading progress of the collection or partition.
