- position
- Int64
This parameter allows the caller to upload data in parallel and control the order in which it is appended to the file. It is required when uploading data to be appended to the file and when flushing previously uploaded data to the file. The value must be the position where the data is to be appended. Uploaded data is not immediately flushed, or written, to the file. To flush, the previously uploaded data must be contiguous, the position parameter must be specified and equal to the length of the file after all data has been written, and there must not be a request entity body included with the request.
- options
- DataLakeFileFlushOptions
Optional parameters.
- cancellationToken
- CancellationToken
Optional CancellationToken to propagate notifications that the operation should be cancelled.
Returns
A Response<T> describing the path.
Remarks
A RequestFailedException will be thrown if a failure occurs.
