getFlushState()

MilvusClient interface. This method tests whether specified segments are flushed.

R<GetFlushStateResponse> getFlushState(GetFlushStateParam requestParam);

GetFlushStateParam

Use the GetFlushStateParam.Builder to construct a GetFlushStateParam object.

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

Methods of GetFlushStateParam.Builder:

Method	Description	Parameters
withCollectionName(collectionName)	Set the collection name. Collection name cannot be empty or null.	collectionName: The target collection name.
withDatabaseName(String databaseName)	Sets the database name. database name can be null for default database.	databaseName: The database name.
withSegmentIDs(List<Long> segmentIDs)	Set an ID list of segments to be tested. Typically the ID is returned by flush() method.	segmentIDs: An ID list of segments.
addSegmentID(Long segmentID)	Add a segment ID to be tested. Typically the ID is returned by flush() method.	segmentID: A segment ID
withFlushTs(Long flushTs)	Input a time stamp of a flush action, get its flush state(optional).	flushTs: A time stamp returned by the flush() response.
build()	Construct a GetFlushStateParam object.	N/A

The GetFlushStateParam.Builder.build() can throw the following exceptions:

• ParamException: error if the parameter is invalid.

Returns

This method catches all the exceptions and returns an R<GetFlushStateResponse> 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.Unknown and error message of the exception.

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

Example

import io.milvus.param.*;
import io.milvus.grpc.GetFlushStateResponse;

GetFlushStateParam param = GetFlushStateParam.newBuilder()
        .addSegmentID(COLLECTION_NAME)
        .build();
R<GetFlushStateResponse> response = client.getFlushState(param);
if (response.getStatus() != R.Status.Success.getCode()) {
    System.out.println(response.getMessage());
}

System.out.println("Flushed: " + response.getData().getFlushed());
