public DataLakeFileInputStreamOptions()

Method Details

getBlockSize

public Integer getBlockSize()

Returns:

The size of each data chunk returned from the service. If block size is large, input stream will make fewer network calls, but each individual call will send more data and will therefore take longer. The default value is 4 MB.

getConsistentReadControl

public ConsistentReadControl getConsistentReadControl()

Returns:

ConsistentReadControl Default is E-Tag.

getRange

public FileRange getRange()

Returns:

FileRange

getRequestConditions

public DataLakeRequestConditions getRequestConditions()

Returns:

DataLakeRequestConditions

isUserPrincipalName

public Boolean isUserPrincipalName()

Returns:

The value for the x-ms-upn header.

setBlockSize

public DataLakeFileInputStreamOptions setBlockSize(Integer blockSize)

Parameters:

blockSize - The size of each data chunk returned from the service. If block size is large, input stream will make fewer network calls, but each individual call will send more data and will therefore take longer. The default value is 4 MB.

Returns:

The updated options.

setConsistentReadControl

public DataLakeFileInputStreamOptions setConsistentReadControl(ConsistentReadControl consistentReadControl)

Parameters:

consistentReadControl - ConsistentReadControl Default is E-Tag.

Returns:

The updated options.

setRange
