This class uses an algorithm designed to aid users in writing simple code that is also performant. The idea is that the caller can write the following pseudocode: using (BlobWriteStream bws = Cloud*Blob.OpenWrite()) { while (moreData) { byte[] bytes = await GetDataAsync(); await bws.WriteAsync(bytes); } } The goal here is to have this code exhibit a sort of double-buffering functionality, where "GetDataAsync()" (whatever that is) is able to run in parallel with the data upload to Azure Storage. This is accomplished via buffering data during the write, and then later uploading it to Storage. However, we also need to limit how much data is buffered, to avoid using too much memory. To do this, continuation after "await bws.WriteAsync(bytes)" will only continue if the stream hasn't buffered too much. The limit on what is "too much" depends on the size of the input bytes[] data, the block size, and the max parallelism factor. Roughly, it's the maximum of 1-2x the input byte array size, and block size * parallelism factor. It's also fuzzy depending on whether or not you include any data that's currently being processed in WriteAsync(), any data that's currently being uploaded, or just data that's stored in the stream's buffer, waiting to be uploaded. The biggest complication and/or likely location for bugs is around error handling, because errors might occur after "await WriteAsync()" has already continued. If some day we consider a library re-design / re-architect, this code would likely be opt-in.

This value is used mainly to provide async commit functionality(BeginCommit) to BlobEncryptedWriteStream. CryptoStream does not provide begin/end flush. It only provides a blocking sync FlushFinalBlock call which calls the underlying stream's flush method (BlobWriteStream in this case). By setting this to true while initiliazing the write stream, it is ensured that BlobWriteStream's Flush does not do anything and just returns. Therefore BeginCommit first just flushes all the data from the crypto stream's buffer to the blob write stream's buffer. The client library then sets this property to false and calls BeginCommit on the write stream and returns the async result back to the user. This time flush actually does its work and sends the buffered data over to the service.

The Encryption Policy on the default BlobRequestOptions must contain an IKey with the new encryption key.

A object that represents the asynchronous operation. The parallelIOCount and rangeSizeInBytes should be adjusted depending on the CPU, memory, and bandwidth. This API should only be used for larger downloads as a HEAD request is made prior to downloading the data. For smaller blobs, please use DownloadToFileAsync(). To get the best performance, it is recommended to try several values, and measure throughput. One place to start would be to set the parallelIOCount to the number of CPUs. Then adjust the rangeSizeInBytes so that parallelIOCount times rangeSizeInBytes equals the amount of memory you want the process to consume.
