Package:

Microsoft.Azure.DataLake.Store v1.1.24

Asynchronous API to perform concurrent append at server. The offset at which append will occur is determined by server. Asynchronous operation. It is highly recomended to call this api with data size less than equals 4MB. Backend gurantees 4MB atomic appends.

public virtual System.Threading.Tasks.Task ConcurrentAppendAsync (string path, bool autoCreate, byte[] dataBytes, int offset, int length, System.Threading.CancellationToken cancelToken = default);

abstract member ConcurrentAppendAsync : string * bool * byte[] * int * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.ConcurrentAppendAsync : string * bool * byte[] * int * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Public Overridable Function ConcurrentAppendAsync (path As String, autoCreate As Boolean, dataBytes As Byte(), offset As Integer, length As Integer, Optional cancelToken As CancellationToken = Nothing) As Task
