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.
