Azure.Storage.Files.DataLake.Models.DataLakeOpenReadOptions

public class DataLakeOpenReadOptions

Optional parameters for OpenReadAsync

public int? BufferSize { get; set; }

The buffer size (in bytes) to use when the stream downloads parts of the file. Defaults to 4 MB.

public DataLakeRequestConditions Conditions { get; set; }

Optional DataLakeRequestConditions to add conditions on the download of the file.

public LayoutAwareRouting LayoutAwareRouting { get; set; }

Determines whether locality-aware routing is used for the buffered range requests issued by the returned read stream. When enabled, the file's layout is fetched on demand and cached (with automatic background refresh), and each range download is routed to the optimal endpoint for the chunk being read. This is a performance optimization only - the bytes returned are identical to a non-locality-aware download. Defaults to Auto, which currently disables locality-aware routing; set to Enabled to opt in.

public long Position { get; set; }

The position within the file to begin the stream. Defaults to the beginning of the file.

public DownloadTransferValidationOptions TransferValidation { get; set; }

Optional override settings for this client's TransferValidation settings.

public DataLakeOpenReadOptions(bool allowModifications)

Constructor.
