public class DataLakeFileAsyncClient
extends DataLakePathAsyncClient
This class provides a client that contains file operations for Azure Storage Data Lake. Operations provided by this client include creating a file, deleting a file, renaming a file, setting metadata and http headers, setting and retrieving access control, getting properties, reading a file, and appending and flushing data to write to a file.
This client is instantiated through DataLakePathClientBuilder or retrieved via getFileAsyncClient(String fileName).
Please refer to the Azure Docs for more information.
